Very pretty baby. I think JC wants to know which blocks came from who, just because she does not want her blocks attached and she wants to know which blocks go together. You are right, the names will not show up if you put them on the back of the blocks you make. Just put an address label on the back of the blocks you make for JC. Does this help?
Yvonne, there are several ways you can do a label for the back. You can send one bigger label for everyone to sign, date and put which row they worked on. You can also add your name, date, and the row you worked on.
Another way is to send 4 smaller labels with your info on all 4 labels for the other members to keep and put on the back of each of their quilts.
