I was thinking you could use plum color to join them since the plum color is for the caregivers.If you get enough interest in the Choose Hope swap, I am definitely in!!
I'm thinking if we had 16 people participate, I'd get 16 different beautiful squares. There r 26 different cancer color ribbons. So I would make 10 more plain colored squares to place randomly through the project. Then crochet the correct 26 colored ribbons and stitch one onto each square. How awesome would that look at your local Cancer Center or Cancer Floor of your hospital, hanging on the wall for patients to see that people all around the country are thinking of them and Choose Hope??
