Elizabrat there is alot of doubles for diamonds and rubies. I still sent each one in a separate envelope because I have a different fabric for the smaller swap. I have 2 containers, 1 marked diamonds and 1 marked rubies. Then as I get them I will put envelope in container according to group. I guess if they are sent together, I'll split them up and just grab another envelope and separate them. I just think I can keep track of them better for me. As I send them out I put any unused fabric in that envelope and keep it until the very end. Sometimes if they ask I return the fabric or I am known to make 2 blocks instead of 1 to send back. Last boom sustraley's fabric sent to 1 member somehow got lost and I had enough to send her so she could make a block for sustraley. It all works out. Just whatever is easier for you.
