Selvedge or selvage? And what is it?

Published on July 4, 2023

Within the realm of textile terminology, ‘selvage’ and ‘selvedge’ often cause some confusion due to their apparent similarity. These terms, which primarily differ by their usage in American and British English respectively, both refer to the “self-edge” of fabric, a tightly woven edge that prevents fraying. Although selvage and selvedge labels are frequently associated with higher-quality denim, it’s critical to understand that these terms alone do not guarantee superior quality. Rather, the true quality of the fabric depends on various factors, including the materials used, the production methods, and the attention to detail throughout the manufacturing process.

Selvedge denim is derived from traditional shuttle loom weaving, resulting in distinct character and texture, as seen in the texture of this fabric.

The origins of selvedge or selvage denim can be traced back to the use of traditional shuttle looms. These machines became less favored during the early-to-mid twentieth century with the advent of more efficient and faster machines. Shuttle looms, although slower and more cumbersome, bestowed upon the fabric a distinctive texture and character. However, as textile producers began to prioritize efficiency and affordability, non-selvedge textiles, produced by high-speed air jet weaving machines, gained popularity.

Unlike selvedge denim, it lacks a self-edge and offers more consistent weaving due to advanced machinery.

Modern high-speed weaving machines significantly outperform shuttle looms in terms of production speed and efficiency, enabling the mass manufacturing of fabrics at a lowered cost. However, the trade-off here is the loss of the characteristic “imperfections” and unique quality that traditional shuttle looms imparted to the fabric. This is one of the major reasons why selvedge denim, despite being slower and more expensive to produce, is still sought after by certain consumers and fashion connoisseurs.

Distinguishing Between Raw Denim and Selvedge Denim

Raw denim and selvedge denim are terms used in the denim industry to refer to different aspects and should not be conflated. Raw denim, or ‘dry denim’, refers to denim fabric that hasn’t been washed or treated after the dyeing process. As such, raw denim can come in a variety of shades, from dark indigo to lighter blue, depending on the dye used. On the other hand, selvedge (or selvage) denim pertains to the method of finishing the fabric’s edge to prevent fraying, often associated with higher-quality production. It’s possible for a pair of jeans to be both raw and selvedge, but they are not mutually exclusive terms.

In recent years, a resurgence in the popularity of selvage or selvedge textiles has been witnessed as consumers have grown more discerning about the craftsmanship and quality of their clothing. The unique quality, texture, and durability of selvage denim, produced on shuttle looms, possess a distinctive charm and character that many consumers find desirable. In essence, it’s the “imperfections” of the traditional shuttle weaving process that sets selvage apart, adding value to it.

However, it’s vital to remember that the quality of selvedge denim can significantly vary. Some manufacturers leverage the meticulous weaving process of the shuttle loom, investing in high-quality cotton and dyes, resulting in a more robust and durable product. Conversely, lower-quality producers of selvedge textiles may merely imitate the look and utilize lower-quality materials, resulting in a less resilient product.

In conclusion, whether you encounter the term ‘selvage’ or ‘selvedge’, it refers to a particular type of denim defined by its distinctive woven edge finish. While these terms often imply higher quality due to their association with traditional production methods, the actual quality can differ vastly. Thus, as a consumer, it’s essential to understand the intricacies of selvage or selvedge denim, the specific brand, and its production methods to make an informed decision when purchasing such products.

Tapering both flat-felled & overlock constructed jeans from the inseam explained

Published on July 23, 2022

It seems needless to say, selvedge jeans should always be tapered from the inseam. However, some people still take jeans to local tailors or dry cleaners, who are not equipped with proper denim sewing machines and expect them to properly taper their jeans.

This photo shows an example of tapering from the inseam in-process. These jeans were sewn with a double-needle chain stitched flat-felled (lap seam), so it has to be taken apart at the inseam. With the selvedge outseam shown at the center, the inseam is then trimmed to slim the leg down. Slimming is done from the hem, up to just above the knee, and eases out at the thigh.

A tailor without a feed-off-the-arm chain stitch sewing machine will never properly taper a pair of jeans with lap seam construction. Instead, they may use makeshift single needle sewing from the hem to the knee area. Leaving the area around the crotch and thigh with the original sewing, connecting the new sewing into the original.

How to taper jeans with a single-needle overlocked inseam

Not all jeans have two needle chain stitch lap seam construction. Some have a single-needle topstitched inseam with overlock construction. We tapered the below Levi’s jeans, slimming the legs down and the excess fabric cut from them can be seen underneath.

Most tailors can handle overlocked jeans much easier than lap seams. Overlock sergers are machines commonly used by tailors. However, similar to how traditional tailors may handle lap seam sewing, they will likely remove the original topstitching to just above where the tapering will end. Then use the serger to sew the new leg shape. Finally, to reach high on the leg, so new topstitching can join with the original, the outseams are opened and subsequently closed after topstitching the inseam.

Process for tapering jeans with overlocked inseams as also seen in our TikTok video:

Cut the inseam to the requested inseam length, plus 3/4″ to 1″ (depending on the hem height)
Remove the single stitch on the inseam
Press the inseam flat & draft the taper lines on each leg
Trim & sew the new leg shape with a serger sewing machine
Press the inseam to remove slack
Sew a new single-needle chain stitch on the top of the inseam
Chain stitch the hem

Depending on the details of the tapering, we first remove the entire original topstitching in order to sew a new unbroken/unjoined line. It doesn’t matter if the taper is to the knee, above the knee, or high into the thigh.

We taper jeans high into the thighs only when we get requests to make the thigh smaller. We always advise, that very little can be done at the thigh. Explaining, that the width of the thigh is in connection to the pattern’s shape. The seat, rise, and curve in the crotch (which affects movement) are all connected. Decreasing the thigh means the curve must be shortened and straightened, which will restrict movement. Taking from the curve also lowers the rise.

In other words, the best we suggest is easing the taper from the knee, high into the thigh, clipping a bit of the curve, thus reducing the thigh to a maximum close to 1/2 inch. We don’t feel comfortable taking much more.

Looking closely, the original overlock stitching can be seen in white thread and the new sewing in tan color. These jeans were tapered high, so we went completely around the crotch.

As demonstrated in the TikTok video below, one of the biggest things that separate our work from tailors and denim specialists is our use of the Union Special feed-of-the-arm chain stitch machine. On single-needle overlock constructed jeans, it allows us to completely topstitch the inseam from hem to hem without opening the outseams.

The Union Special is advantageous with selvedge jeans because you don’t want to disturb the outseams. Tailors who have to rely on tapering at the outseams will destroy the beauty of the selvedge jeans. The photo below is an example of what can happen when you give your jeans to a local tailor who doesn’t specialize in or understand denim. Luckily, he later did some research, found us and we saved his jeans.

Denim/What is?

What is chain stitch hemming?

Published on January 8, 2020

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?

Published on June 20, 2018

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.
