So, I thought I was finished with
Simplicity 3640. At the store yesterday, they did not have a 20" separating zipper, so I picked up a 24" separating zipper. Now, I realize that the end of the zipper goes below the edge of my jacket. Is there a way to shorten it? I know with regular zippers, I'd just sew some straight stitches at the desired length, but will that work for the separating zipper? I really don't want to have to take out the zipper, especially since I didn't even see a space for 20" zippers at the store... Please help!
