Here's a get well quilt I did for my brother-in-law in 2008. Same principle: sent muslin ironed to freezer paper and pre-cut into rectangles, with the corner seam allowance marked in pencil. I had them use supplied Pigma Micron 05 (archival ink) pens. Most of these were signed by sixth graders. The rectangles didn't fray because the freezer paper stabilizes the fabric, also making it easier to write on. If you just supply the pre-cut squares, you can take your time making the quilt when you don't have so many other things to do. If you don't get enough signatures, you can evenly disperse them throughout the quilt design. I ironed them to set the ink and they are permanent. Good luck with your endeavor. It will be a fantastic memento of your special day.[ATTACH=CONFIG]407531[/ATTACH]
