Ok. So I have been sewing away on my 15-91. I have made a baby quilt for my niece arriving in December. Now I would like to start on some of these upcycled leggings for her. But the instructions call for a zig zag stitch. What tricks can I use for the same effect with the straight stitch? I am sure skirts were made with this type of elastic back when. I've just never used elastic before..... thoughts?
