Sure could use some input. I just finished hand quilting a lap quilt. Used the wash off blue marker for my quilting lines and never had a problem before. As per the directions on the marker package, I gently rubbed with a wet clean cloth. Most came off without a problem. A couple of areas (on a bright white on white fabric no less) left a brownish/yellow cast. At no time did I apply any heat to it and the markings were on less than one week.
Only thing I can think of, it before I marked the quilt top, I pressed it using the Bounce Ironing Spray. Do you think this was enough to cause a chemical change? Odd that it isn't reflected through the entire white on white fabric.
Any suggestions? Should I soak the entire thing? In just plain water? I need to bind it before I do anything involving full submersion though. Thanks for your help.
