PAY CLOSE ATTENTION:
The following picture shows my original materials. HOWEVER, I do NOT recommend the Snap Plier tool that you see in the pic. It was expensive ($22.49), and it didn't work for me. Maybe mine was defective, but there is a much cheaper/easier tool to use.
I do recommend this tool. It was only $7.49 and much easier!
Cut a strip of ribbon about 17-18 inches....depending on how long you would like the strap to be. Seal the ends of the ribbon with a lighter. Feed one end of the ribbon through the mitten clip and fold the ribbon in half. Use pins to hold the ribbon together. The ribbon should now appear to be about 8 1/2-9 inches. (**You do not have to double the ribbon, but I wanted the pattern to appear on both sides.)
Sew along the edges in order to connect the ribbon together. Make sure that you also sew directly below where you fed it through the clip.
Fold the end of the ribbon over about 1 inch. Follow the instructions on the back of the snap tool package to add the snaps. It is as easy as that!
VOILA!
