When both my boys got married I made "rail fence" squares with the center a light color for the guests to sign and write a blessing on. The squares were already made up, that way they were uniform in the colors the kids wanted, and size. I brought 2 small clip boards with fine sand paper on them and permanent marking pens (so the quilt can be washed). After the wedding I put the quilt together, quilted it and gave it to them on their 1st anniversaries. :)
