Thank you for asking this question. I have a quilt that has been on hold here for awhile and the reason is this problem. I am 'fixing' someone else's work, not my favorite thing to say the least. Wonderunder was used on the majority of memorabilia on this quilt to hold things down instead of sewing or quilting. A big mess. Now at least I know how to get rid of the Wonderunder! This is a major undertaking that I have on my hands. Will you please post back to we all know just how well you were able to get the majority of this mistake off. Thanks
