My aunt had a pattern like this she would make for everyone for Christmas. I still have the original one she made for me in my Christmas stuff and I take it out every year and put it on my coffee table. After she passed, I took it and made it my own. Now I want to share it with you! there is 21 rounds. You could do 21 colors but 3 to 5 is best. This pattern has examples of other color ideas. I think picking a color is the hardest part.
