I mentioned to a friend that I was taking in a pair of my agility pants, and she asked me how I did it. Hence this series of commented photos of the process.
This is the middle back of the pants (outside) before I did anything at all.
And this is the inside middle back before I did anything.
The next step was to sew the drawstring in place so I could use it after I was done. The way I did it, it won’t slide through the middle back, but I know from experience that doesn’t matter. I just zigzagged across the sides where I planned to cut.
Next I cut a triangle out of the middle back that was a little less than the amount I needed to take in.
Then I overlapped the two sides and zigzagged one side on top of the other. I went over the seam twice to make it strong.
No, it’s not the classiest or neatest job ever, but I always wear a sweater or a t-shirt over my pants, so no one but my dear readers will ever see it. Besides that, I’d be way less embarrassed for someone to see that seam than I would be for my pants to fall down while I’m running!
