I have always been a bit hopeless with needle and thread. Now DD1 has started ballet classes so I have to deal with those elastic bands that come with ballet shoes. First of all - do you cut them to the right length or do you fold the unused bits under when you sew them on? How many stitches do you use on each side? Do you do two rows of stitches (top and bottom) or just one? And do you use double thread or just a single one? Thanks people!
