What is a Bar Tack (Bartack)

Published on

What is a “bar tack” (also spelled “bartack”)? This is a question we get almost every day because our denim service is one of the very few that offers bar tacking. The close-up image above shows two red bar tacks sewn onto the hem of a pair of Gustin blue jeans. When you choose to add bar tacking in the dropdown box of our chain stitch hemming service, this is the type of stitching that will be added.

First, an explanation for the majority of our customers who are interested in having their jeans hemmed. The close-up image above shows two red bar tacks sewn onto the hem of a pair of Gustin blue jeans. When you choose to add bar tacking in the dropdown box of our chain stitch hemming service, this is the type of stitching that will be added.

Brands like Gustin, Nudie, and Brave Star jeans have bar tacks sewn over the chain stitching on the hems, both as a branding identifier and to reinforce the sewing. Although they add a bit of extra security by preventing the chain stitch from unraveling, they are not found on the vast majority of jeans. We usually inform our customers that it is not necessary to add them.

"What is a bar tack?" pointed out on Nudie jeans with bar-tacked chain-stitched hem.
Nudie blue jeans are typically sewn with a chain stitch that extends off the hem with a bar tack on the seam.

Definition Summary

A bar tack is a machine-made stitch with a zigzag pattern used to reinforce areas on clothing that experience high stress, such as where belt loops join, pocket corners and flaps, hip seams, and the fly of jeans.

The Union Special 43200G: A Unicorn or One-Trick Pony?

Published on

Denim nerds, get ready for a reality check. I’m about to debunk some of the myths and misconceptions about the Union Special 43200G that have been circulated for years by brands, publications, and online communities.

As is the case with many things on the Internet, exaggerated claims can quickly become folklore by the regurgitation of stories that weren’t well thought out from the beginning.

The well-told narrative that the twisting at the hem is caused by a technical error, feed dog flaw, or differential defect in the inner workings of the Union Special 43200G is flawed in and of itself. The roping effect has been overcomplicated to the point where denim fans who don’t know any better will believe that the Union Special 43200G is the only sewing machine capable of producing twisted and puckered hems with chain stitch hemming.

In my research into what denim enthusiasts are being led to believe, I easily discovered statements that I believe are misleading or false. Here are a few examples:

“Any Union Special without the folder will not create the roping effect.”

“There is only one way to chain stitch a selvedge denim hem and that’s on a folder equipped Union Special 43200g. Why you ask? These machines create a desirable roping effect on the hem which is actually caused by a feed differential defect.”

“Roping comes from the 45 degree angle of break-in that makes the hem look like a rope. It’s become part of true denim DNA. Without it, jeans don’t look right to us. And the crazy thing is this comes from a flaw in the Union Special that makes it create a slight twist.”

“Union Special company seems to have replaced the 43200G with other machines in a quest to replicate the same stitch and make it easier to use the machine but this has reduced the tension on the thread. This means you don’t achieve the same roping/puckering as you would with the original.”

In reality, the roping effect is simply caused by seams that are not lined up.

Example of a misalignment of both seams on a jeans hem will cause a shift and rotation in the direction of the misalignment. This is the roping effect on denim.
The graphic shows how misaligned hem seams create a shift and rotation. This is the roping effect on denim.

The roping effect is simply caused by seams at the face and undersides of the hem not being lined up. Twisting occurs when the inseams shift in one direction, resulting in the roping effect. The effect becomes more visible with aging and washing. Sometimes factories do this unintentionally, and other times a brand’s designers may request a factory do it on purpose. Most factories make an effort to align the seams, which may be the reason why most jeans do not exhibit a significant degree of twisting.

Close-up example of the roping effect on a pair of light-washed Levi's jeans with chain stitch hemming and frayed hem.
Example of the roping effect on a pair of light-washed Levi’s jeans with chain stitch hemming and frayed hem.

Furthermore, the stitch type is not a factor in creating the twists and puckers, as seen in the reference example photo below. I, too, was once swayed by rumors and stated in my tapering video that the tension of chain stitching contributes to the roping effect.

Busting the myth that the Union Special 43200G does not cause roping effect by showing twisting on a hem sewn with a lockstitch machine.
These hems without chain stitching show that the puckers and twists that make up roping are not caused by the type of stitch.

Don’t misunderstand me. I think the well-beloved Union Special 43200G is a beautiful old sewing machine. However, production was halted for a reason. It was most likely not due to a differential flaw, cheaper lockstitching, or other nonsense being repeated or made up. The truth is that it only does one function. Although it performs well, some sewing machines can perform the same function as well as other operations.

Purchasing a sewing machine that only does one thing over machines that do multiple tasks equally well or better is a bad idea for factories that must make sound economic decisions. This is most likely why production was halted, as with most discontinued products.

What is Jeans Hemming Explained

Published on

Summary

Jeans hemming is the process of shortening the leg or inseam length of a pair of jeans by removing some of the fabric from the bottom.

These photographs demonstrate the before and after effects of hemming alterations made by Williamsburg Garment Company to shorten the inseam of jeans to demonstrate “what jeans hemming is.” The top photograph features a pair of Pure Blue Japan jeans. It displays the altered inseam and leg openings as well as the portions of the hem that was removed.

The below image displays a pair of raw denim jeans with their original hem and full inseam length. A chalk line on the jeans marks the hemming cut line, which also includes a 1/2-inch double fold (1-inch).

A pair of raw denim LeRoy Strauss jeans are shown at their original length, and a chalk line marks the hemming cut line.
A pair of raw denim jeans with yellow chainstitch inside the hem are marked with a chalk line which represents the cut line.

The majority of jeans are sewn with chain-stitched hemming. The average hem measures roughly 1/2 inch tall. A tailor or seamstress double folds the raw edge after cutting to the hem (leg opening). Since each fold measures approximately 1/2 inch, the inseam length must be increased by 1 inch to reach the desired length.

To see what we mean by double folding, and the process of hemming in action. Watch our video “Chain Stitch Hemming in 87 Seconds.”

Tips for Professionally Hemming Your Denim: The Simple, Affordable Way

Published on

So you splurged on that vintage-looking pair of Gap 1969 jeans. They are everything you were looking for, but about 4-to-5-inches too long. Now what? You don’t want to wear them rolled with a huge cuff – or even have them stacking over your shoes. You want to make them one of your go-to jeans, so you need them to fit right. Here’s how you can make that happen: With fast professional chainstitch denim hemming service that’s available from any city or town in the USA! We make our alterations services simple and both affordable and easy to execute. Read on to learn how we can help you achieve the perfect fit:

What is a Chainstitch Hem?

A chainstitch hem is a technique used in most jeans. It’s a fairly common and durable stitch that is found on most jeans. As seen on the above pair of Gap 1969 jeans, you’ll want to ensure when shortening your inseam, the jeans have the same style of sewing as the original store-bought jeans. That’s with chain stitching and thick, heavy threads. Both are not options not usually found at local tailors, cleaners, and even department stores or a brand’s in-store alterations services. Read more on chainstitch hemming on our blog.

The Catch-22 of Denim Hemming

Unfortunately, there are DIY techniques and non-professional denim tailors who offer what’s called an Original Hem alteration. They say you can retain the original pre-washed edge on the leg opening, but they don’t tell how bad your jeans will look on the inside or how you will lose the flexibility of the hem.

Final Words

Original hems are a bad idea. Don’t let anyone talk you into this style of alteration. We get lots of jeans sent to us with requests to undo this alteration and re-hem the jeans correctly with chain stitching.

The pre-washed edge on the leg opening, as seen on the section cut from Gap 1969 jeans comes back in time with washing and wearing. If you want to speed up the process, you can rough up the hem with sandpaper, a sharp blade, or an electric grinder for the shredded look. For fast fading, wet and wrinkle the hem, then rub in a small amount of bleach on the high points, and dip the hem in cold water to halt the fading. Machine wash the jeans after.

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

Published on

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.

Shop Tapering Alterations

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:

  1. Cut the inseam to the requested inseam length, plus 3/4″ to 1″ (depending on the hem height)
  2. Remove the single stitch on the inseam
  3. Press the inseam flat & draft the taper lines on each leg
  4. Trim & sew the new leg shape with a serger sewing machine
  5. Press the inseam to remove slack
  6. Sew a new single-needle chain stitch on the top of the inseam
  7. 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.

Williamsburg Garment Company quickly explains how to professionally taper jeans. Setting us apart from common and amateur tailors, we take the pants apart, redraft the shape, then sew them back together following the original factory’s construction. #denimhead #selvedgedenim #denimtailor #taperingjeans

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.
