Mavis,
I'm obviously no expert, but I have made several machine appliqued quilts. I use the Heat 'N Bond Lite -- never the "heavy" or "ultra"-- that's going to be way too stiff for a quilt. If you use the ultra, you are letting yourself in for a lot of grief -- even the lite will, on occasion, gum up your needle, but it's certainly not as extreme as the "ultra". I think the Pellon Lite Fusible is your best bet for a stabilizer for a T-Shirt Quilt.
That use is not recommended even by the manufacturer, and I really don't think the sales lady who sold that to you is correct -- what she uses it for is no doubt different than what your project is.
