How To Repair Selvedge After Denim Alteration

Note: This post is a guest post submitted by David Zheng. If you’d like to follow him and his work, check out his tumblr.

Denim adjustments of any scale or nature is not always a seamless experience, particularly when it comes to anything beyond basic hemming. For instance, many are often wary of tapering their selvedge denim because of how unattractive the selvedge may appear afterward.

I faced this same quandary after having my denim tapered – compared to its pre-ops state (see below), the selvedge was left enlarged and lost its clean, parallel construction. Thus, I turned to this step-by-step process in an attempt to preserve the revered denim detail to its original form.

Pre-Alteration Selvedge

  • Name: 3sixteen+ 12BSP Left-Hand Twill
  • Weight: 14.5 Oz.
  • Fit: Straight Leg
  • Denim: Unsanforized, left-hand twill 100% Cotton

Step 1 – Measure

The denim had a leg opening of 7 inches (14 inch circumference) and I had them tapered down from the knee to roughly 6.5 inches (13 inch circumference).

As a result, the selvedge was widened by approximately 1/2 inch, or the halfway point on both sides.

Step 2 – Plan

To properly adjust your selvedge, you’ll need to gather the following instruments:

  • A sewing needle
  • Dark coloured thread
  • A pair of sharp scissors
  • An iron

Once you have all of these instruments, proceed to cut the selvedge along the hem (not length-wise up the selvedge). As mentioned in Step 1, after alterations my selvedge was widened by approximately 1/2 inch or at about the half-way point on both sides (green lines in above image).

The blue arrows above roughly illustrate where and by how much I “brought in” the selvedge.

Step 3 – Prepare the Selvedge

Next, fold the selvedge in a way so that it resembles the unaltered look. It’s difficult to clearly explain how to proceed with this step, so see below for an idea of how the folds should form.

Step 4 – Sew The Folds Together

After you have your selvedge prepared, take the needle and thread and sew under the top flap fold. Sew from right to left as shown below.

In practice – sew along the length of the selvedge, cut, and knot.

Step 5 – Iron

As the final step, iron the selvedge to achieve a more crisp and clean look. Although it may appear sloppy at first, once it has been pressed and is cuffed, any imperfections will be barely noticeable.

The End Result

A few caveats:

  • Unable to single cuff – the frayed ends nearest the chain stitching is unflattering
  • Indescribable pain of cutting perfect japanese selvedge denim will surely be felt
  • The end result will not be without imperfections
