I too made a wedding signature quilt. However, I did make the quilt top and take that with me to the reception. The bride's brother (an adult) was in charge of getting people to sign/leave a message on the blocks that were surrounding the center motif as they arrived at the reception. There was freezer paper ironed to the back of each area to be signed by pigma pens. Yes, do have more than one pen available. It was a small wedding so it all worked out fine .... except for one fairly old uncle who signed the block upside down but the bride treasures that block just the same/all the more. The quilt was quilted after the wedding with wording in the outside border. The center motif matched the flowers that the bride was carrying. This is such a wonderful gift to the family that it is wonderful that you are putting forth the effort to make this for them. Don't sweat it if there are a few crazy signatures. Good luck and enjoy!
