Tanya, are you absolutely sure it's Wonder Under that you are using? I found Wonder Under too stiff for bed quilts, especially when layered. When you say it is lightweight and gives a wonderful feel to the fabric, I have to wonder (no pun intended!) if we are using the same product. Granted, it was years ago that I tried Wonder Under. Maybe it has changed since I last used it??? I can see using it for wallhangings, but much less so for bed quilts.
