BellaBoo - Thanks for the info. Like other posters, I don't have a tub big enough for my large mat to lay flat.
Jan in VA - Do you think I could put my mat on a table (non wood) and spray it down and then let it sit overnight or do I need to have the wet bath towels?
QuiltPat - Now, why didn't I think of about duct tape! That would keep it from getting worse. Thanks for the idea!
Tessagin- I quit buying good scissors for that reason also. Dropping them on basement concrete floor really does a number on them. I have at least two pair sitting in the closet that I can't bring myself to throw away.
