I made my granddaughters blocks for her guests to sign...the adults did well, but they didn't pay attention to their children and a the signing was during the meal after the wedding, and several blocks were scribbled on, messed up really bad by youngsters...so there was going to be shortage of blocks, but she picked out the best ones and wanted them in her quilt...so I made the quilt and she was happy....I had enough fabric to cut new blocks to have the correct number for the size quilt she wanted....So my only advice is have someone in charge of the block signing..table...my granddaughter learned that lesson the hard way...other than that the wedding was beautiful...and she uses the quilt on her bed all the time...
