If you are having trouble with the getting the interfacing to fuse to the lame... I have been known to cheat and spray baste the interfacing to the lame. I did this when I have interfacing that was not a fusible, and did not want to buy more.

Thanks about the avitar--hard to tell from picture, but it is a wall hanging I made (no pattern). Well thanks for all your ideas, but I gave up on the lame, decided it wasn't worth the trouble!!!!!!!!!!!!!!!!!!
