My guild holds a demo meeting usually every February. It is a chance to have members show other members a technique, how to use a tool or how to make something. This is my demo.
Cut the circle out, you can adjust it if it is not the right size. Repeat to make 3 more in smaller sizes.
Glue them down with some liquid stitch.
There you go! Below are some that I made for friends in different colors.
Have fun with this!
