I am getting married August 13 and would like to have guests sign and or draw on a fabric square instead of a guest book and then put them into a quilt. My question is will sharpie permanent markers work and do I need to treat the fabric squares with something before hand to stop the markers from bleeding? I want to stop the signatures or pictures that may be drawn from distorting, or from fading on the first washing. Any suggestions will be greatly appreciated. Thanks.
