Found this kit at Big Lots for only $2.50, so I bought it. Came with a few extras including a piece I used as a strap (needed one on my other cover but never made one).
Kit was suppose to be all hand sewn, but I did everything in my machine (including sewing a gathering stitch for the yo yo). I did the the button and yo yo by hand. The little Velcro pieces stick on, but I added a center straight stitch to keep them on. I did both yo yo because I want sure which one to use. Used the one that matched the step.
