I used 5" circles. The nice thing about the ornaments is they come with their hanging string already attached so I don't have to worry about attaching anything the the YoYo except the ornament. They work up so fast with the glue gum and lots of cute fabric scaps in holiday patterns.
I made 400 of them and donated them to one of the schools in my district so they little children can sell them at their craft sale around the holidays. I have 200 more made and once I have a total of 500 more I will take them over as well. Got a great deal after the holidays last year on the minis.
