What is an Original Hem alteration?

/

An original hem also called a European hem, or euro hem is an alteration method where the goal is to shorten jeans and pants without losing the original manufactured hem. This alteration technique is a perceived value on garments with pre-washed or aged hem edges to those who do not want to lose the look.

An Original Hem alteration on a pair of Gustin selvedge jeans notes the construction details of one of the many techniques. Each method has a visible seamline from re-attaching the hem.

This method of hemming is preferred among sewers with home and common-duty industrial machines. It allows them to dodge sewing through multiple layers of denim fabric required in traditional jeans hemming. Besides preserving tatter hem edges, some techniques preserve the manufacturer’s stitching above the hem, which is too thick for home machines, and usually not stocked at most dressmakers and tailoring shops.

Another method of Original Hem alteration has a clean inside construction but is stiff and uncomfortable around the ankles

The alteration method above has a clean inside construction but its construction style causes the hem to be stiff and ring-shaped. The customer who sent this pair in removal and re-hemming complained it was annoying to wear.

Denim enthusiasts and those generally knowledgable about jeans avoid original hem alterations. It is an alteration procedure typically advocated by DIY diehards and non-denim experts because it is generally easier for their equipment to handle. The tailor’s selling point of the process is the preservation of the store-bought hem. Void in the conversation is the annoying inside bulk around the ankles, goofy seamline, or stiff ring-like shape of the cleaner sewn version of the alteration – and the fact that the aged look of the hem will naturally come back through frequent washing and/or wear.

Denim jeans and like-constructed pants are predominantly sewn with chain stitching at the hem and heavy threads that can withstand harsh washing, not typical in other garments. However, even denim lovers more knowledgeable than the average mom about jeans and workwear can get talked into an original hem alteration. Either that or don’t ask the right questions in choosing a hemming service. Have a look at a few examples of jeans and pants sent to us in need of rescuing.

Iron Heart fans should be warned, that the photo below could be extremely upsetting.

The photo shows a pair of Iron Heart jeans as a prime example of bad tailoring. The jeans were tapered from the outseams, destroying the selvedge, and then shortened with an original hem alteration.

This is a prime example of bad tailoring. These rather expensive and high-quality jeans were tapered from the outseams, destroying the selvedge. Not to go far enough, the tailor topped them top off with an original hem alteration. Here there is no reason to save an aged-looking hem edge. The obvious reason for using this hemming technique is the lack of equipment able to sew through the heavy denim typically found in Iron Hearts jeans.

What is chain stitch hemming?

/

Chain stitching is a type of stitch produced by a sewing or embroidery machine. The name chain stitch comes from its looped chain-link-like appearance. In sewing, a chain stitch has a single stitch line on the top side and a looped chain-like stitch on the bottom side.

Single, double, and triple-needle chain stitching is popular in denim clothing and similarly constructed garments. It is usually found on high-stress seams which often incur stretchings such as the center seat seams, yokes, panel seams, inseams, and waistbands. The triple-needle is more often used in workwear.

Tension in the stitch pulls the fabric into a slight pucker, allowing a bit of stretching. A favorite in garment manufacturing because it provides a strong durable stitch that can easily be undone if needed. The tension creates a decorative puckering effect which is especially visible on denim seams and hems, as the fabric shows signs of aging, washing, and wear.

What is hemming?

Hemming is the sewing process of shortening the length or finishing the bottom edge on a pair of jeans or pants. Hemming uses a method of double folding into itself the raw fabric edge of the leg openings to make a clean smooth edge.

What is chain stitch hemming?

Chain stitch hemming is when a pair of jeans or pants are hemmed with a chain stitch sewing machine. The hem of most jeans is traditionally sewn with chain stitching about 1/2″ above the bottom edge. Some makers choose to make the height of the hem taller or shorter as a choice of design aesthetic. The below photo is an example of a chain-stitched hem with a traditional-sized hem.

Why are some jeans made with a regular stitch at the hem?

We see jeans without chain stitching predominantly in the work of novice denim brands or designers inexperienced in the category of denim. However, being a neophyte is not the rule as seen on the below hem of Levi’s jeans. Even the biggest most celebrated brands sometimes use factories accustomed to producing low-end / discount denim and commonly disregard chain stitching if not a design decision.

To be clear, we don’t know why any brand would purposely choose to use a regular stitch at the hem, especially if they are well-established denim brands, however, some are known to do so. Take A.P.C. for example, which is a major French brand that has a generally well-educated denim customer base and has been pretty successful in making jeans for a long time. They purposely choose to go with a hem fold that is larger than most jeans, plus use a single needle stitch (trouser styled). This is obviously an aesthetic choice.

That said, customers that send us A.P.C. jeans for hemming or tapering, almost always request traditional chain stitching and hem size. Very rarely do our alteration customers request trouser-styled hem construction, which may be an insight into the thinking of U.S. enthusiasts.

What’s the difference between raw denim and selvedge denim?

/

Here is everything you need to know without going into great detail about raw denim’s history or production. Raw denim fabric must first be understood in order to understand what raw jeans are.


Raw denim is simply denim fabric that has not been washed, dyed, soaked, or otherwise exposed to water.


Raw denim is simply denim that has not been washed, colored, soaked, or otherwise exposed to water after the weaving process. What makes denim “raw” has nothing to do with its color, weight, maker, dye, or the fact that it is selvedge or not.

Raw denim is also called dry or hard denim, but it shouldn’t be confused with selvedge denim, which it often is. In the image below, you can see examples of the two different types of raw denim fabric used to make denim clothing. The most common type of denim among denim enthusiasts is selvedge, which refers to the weaving process of the fabric. It has clean-self finished edges or “self-edge” which are used in finished garments by cutting selected pattern parts to the edge of the fabric. Wide goods or non-selvedge denim (pictured in the foreground) is woven with frayed edges which are discarded after cutting.

Is selvedge better quality denim?

Don’t be fooled by the name selvedge into believing it’s better denim. Quality standards, like other items, will vary depending on the provider. Both selvedge and non-selvedge denims are manufactured in varying grades. Frequently, mass producers of low-cost jeans use suppliers who are not known for producing high-quality denim. Do your homework since some mass-market brands will leverage the cache of mills recognized for creating premium denim to make cheap denim that looks the part.

Why is selvedge denim more expensive?


For fabric mills, weaving selvedge denim is more expensive. For brands, the cost of manufacturing garments produced with selvedge denim is higher. As a result, selvedge denim products typically sell at higher costs within a brand’s style assortment.


Rolls of selvedge denim and non-selvedge regular raw denim are side by side to compare raw denim vs selvedge.

Within a brand’s style range, selvedge denim jeans are more likely to be more expensive than non-selvedge models: To begin, unlike non-selvedge denim, which can range from 57″ to 64″ wide, selvedge denim is narrower, ranging from 28″ to 34″ in width. This means that a pair of selvedge jeans may require roughly double the amount of fabric as a regular pair of jeans. The pricing of the fabric is the second factor to consider. Selvedge costs a few dollars extra per yard (depending on the supplier) because it is typically woven on older, slower looms that create fabric with a high rate of flaws, whereas modern looms make wider (non-selvedge) denim with fewer faults at faster speeds.

The images below show “Markers” for jeans. Markers are patterns for each size range that are printed on paper and used by the cutter to trace the cut on the fabric. The pattern pieces on the Markers are arranged to minimize fabric waste. Selvedge Markers are shown in the top image, and non-selvedge Markers are shown in the bottom image. This example shows two pairs of jeans cut on the narrower selvedge denim would require nearly 6 yards of fabric, while two of the same sizes cut on the wider non-selvedge would use about 2 1/2 yards of fabric.

Mastering the rules that go along with owning a pair of raw denim jeans can be a chore to some. This is one reason some opt for pre-washed jeans. However, for raw denim aficionados, the rewards of naturally aging from a pair of raw jeans out weights the alternative.

Know the differences between naturally aged raw denim jeans and factory washed

People new to raw denim and those who love jeans, but only know them in the pre-washed form, often can’t tell the difference between a naturally aged pair of raw denim jeans and one that is purchased pre-washed. However, if you fall into this category don’t feel bad. You may be surprised to learn many of the people earning salaries as designers, editors, and denim buyers at some of the largest department stores, publications, and brands making the decisions on what jeans are sold, seen, and made, don’t know the difference either. I can’t tell you how many times one of the aforementioned asked about a pair of my raw denim jeans (new/unworn) and referred to them as a dark wash.

Below, I placed two jeans side by side to compare naturally aged jean which started as a pair of raw jeans and premium washed jean, which was designed to replicate dark-aged jean and then I detailed the attributes. Both are Williamsburg jeans. Although we take pride in trying to recreate really authentic-looking aged jeans, there is really just no substitute for the real thing. However, if you seek a worn, broken-in jeans and don’t have the time or patience to weather a pair of raw, please opt for washed jeans with authentic-looking attributes and try to avoid washed jeans that were meant to look aged but look more like jeans decorated with harsh white spots and lines drawn on them.

WHISKERS

Named for obvious reasons, whiskers are the most difficult to imitate and can be the defining detail that makes a wash look artificial or authentic. Real whiskers develop texture over time as the jeans tuck and fold in a repeated manner, with the highest point receiving more abrasion, removing more indigo, and the lower less fiction, which stays darker. High stress at the hip area causes the fabric to bend horizontally. In the early years of whisker reproduction, workers used clamps and tacks with resin to harden the texture in place, in an attempt to give jeans a realistic look. The drawback of making textured denim with resin is that it weakens the yarns. Too much resin on jeans may look good, but the fabric becomes brittle and easily tears. In about 2003, as I was seeking to create more authentic-looking whiskers, I created a new way to add texture and naturally shaped wrinkles to jeans, which is now used at factories all over the world. You can read more about that on the Maurice Malone website.

THIGH, KNEE, AND SEAT ABRASION

The second most important parts of a denim wash are the thigh and seat abrasion. In general, these areas usually take the most beating, along with the knees. In hand sanding, the factory worker usually starts out making the whiskers followed by the thigh, then seat sanding. Lower-quality washes often use sandblasting for speed. This is why with many low-priced and mass-market jeans, the aging at the thigh is bright white or looks like big spots. Sandblasting, although faster is harder to control in the manufacturing process. It also lays down an even amount of abrasion which doesn’t look natural. These areas are finished off with potassium to quickly fade sanded areas. Again, in lower price jeans, the chemical is sprayed on, while some higher-priced manufacturing sometimes applies the potassium by brush for a more natural uneven effect.

CHEVRONS

Chevrons are stretch marks on the inner thighs. They are usually more intense higher in the crotch and fade out closer toward the knees.

KNEE STRETCH MARKS

One of the characteristics routinely avoided in premium washes, but always seen on naturally aged jeans is stretch marks created by the stress of bending the knees. These marks usually extend over the outer seams and fade into the wrinkles at the rear side of the knees. 

REAR KNEE LINES

Not pictured, but sometimes added to washed jeans are the honeycomb-like texture that forms at the rear side of the knees from walking and the sitting position. Wash factories tend to overdo effects more often than not and this feature is not so easy to replicate, so most of the time, the rear knees are either avoided or badly done. The worst example of this is the look of lines drawn at the rear sides of the knees, usually with the placement low on the calf.

WAISTBAND ABRASION

Most often, this wearing away is seen on men’s jeans from the friction caused by wearing a belt.

FLY ABRASION

Fly abrasion can take many forms, depending if the jeans have a button or zipper fly. It also depends on how loose or tight the fit of the jeans is. When you see whiskers across the fly, it is affected by the stress from the hips and this usually occurs with button fly.

What are whiskers on jeans? How are they made naturally and commercially?

Denim enthusiasts know the best whiskers are made by starting with a pair of dark raw denim jeans and just wearing the hell out of them. An example can be seen in the image below of a 1-year-old 15-oz pair of Williamsburg jeans. On the other hand, the average consumer may be asking, “what are whiskers on jeans?” Because they only know the jeans they buy in stores come with a worn-in look and can’t tell what looks natural and what looks manufactured.

If you don’t have the patience to break-in a pair of raw jeans or can’t deal with the rules of wearing them – choosing rather buy pre-washed ones. You should at minimum be educated on what looks real or good in terms of washes. This is the first article in a new series where we break down many of the effects seen in naturally aged denim jeans. We will explain how the effects are created to make prefabricated washes look naturally aged.

What are jean whiskers?

Whiskers, also called mustaches, hige, crease lines, etc., can be seen on the jeans below, which formed naturally from the state of raw denim jeans. Lines from repeated stretching and pulling motion develop at the front hip area. Crease lines extend out from the crotch and across the out-seams of the hips. As raw jeans age. Abrasion on the high points of the surface fades and becomes brighter than the surrounding areas as indigo or dye rubs off.

How to put whiskers on jeans

On pre-washed or commercially processed jeans, fabricating whiskers is one of the most copied and difficult effects to achieve. They are artificially created by hand sanding the jeans before they are washed and still in “raw denim” form. On lower-priced jeans, the effect usually looks fake, like drawn white lines. On jeans that garner higher price tags, sometimes known as premium denim, more time and effort is spent to make the whiskers look as real as possible by fading them in and out, mimicking high to low points.
