Thanks for all of your ideas/solutions. I'm really hoping that I did not set those markings in, also. I did try rubbing alcohol last night on a test sample and it worked. So I'm going to try that. With regards to Roxanne's website....I found several ideas there that I previously had tried but no luck. I have my fingers crossed that the alcohol will work. I did find online the spray that someone mentioned. I may see if I can try that.
If nothing else, I will try to wash the quilt. It is a big queen size quilt. This would be a last resort kinda thing, though. Thanks again.
