Our niece is getting married in March and she asked me about making a signature quilt for guests to sign instead of a guest book. There will be 80 blocks for people to sign then I'll assemble and quilt it as their gift. Here is the general idea:
I'll iron freezer paper to the back of the white squares for stability in signing. First, I'll draw straight lines on the back of paper as guidelines--they will be visible through the white fabric. I'll trim all the blocks to size after the signatures are done.
Take a look at Patchwork Times blog to see what others have on their design walls.
