The blue was great and super stretchy. It was also $2 a yard and I bought almost 4 yards of it. For each one, I cut them in thirds so they were 20" wide. Then I cut one of the thirds in half and sewed the half onto the longer one (a straight stitch and then a zig zag). The line ends up being right at my son's shoulder, but maybe no one will notice.
So I have two to give to friends now...or keep them because the cutting and sewing skills are so poor!
