I have the yo yo makers. I like them because I don't have to cut circles, I use fabric squares and then trim to fit after the fabric is in the maker. The Jumbo size makes a finished
3 1/2" size yo yo. The large size makes a finished 1 3/4" yo yo. The extra large makes a 2 3/8 finished yo yo.
Using the makers, you don't have to baste the edges, the edges are automatically turned under. There are online videos showing how to use them. Most are on youtube.
