I love using it because it's even lighter weight than the Lite and is barely perceptible under raw edge applique, but . . .its impossible to use by ironing on a wrong side, then putting right sides of fabric together to sew and then turn right side out. Even a Teflon foot won't sew on that stuff.

It irons on very glossy looking. . .i can completely see how it could be glue
