I was thinking about this today and then noticed that in my hands was Terri's IRR center. It is a large area of applique done with that wonder under stuff I think. Anyway, it is very stiff under the applique. SHe folded it and it went in the mail from Guam to TN. I pressed it and now I've wadded it up working on it, so I'll press it again, but it seems to be no problem at all....
