This lovely ring rests on your index finger as you perform your various crafting tasks. When you need to increment the counter, simply slide your thumb over. Can be used for a variety of counting purposes, but for the yarn crafters out there the end pieces can be printed with a simple hook for holding yarn.

The A and C pieces go on the ends, and you will need one of each. The B pieces have the numbers on them and you will need to print two of them. I made some marks with sharpie to mark which set of numbers was the one I was working with
