I use it all the time for lots of things. Quilting patterns, drawing, block construction. Lots of things.
I tried using a spray to adhere it to the quilt. Unsuccessful for two reasons. The spray I used was not 505 but Duro all purpose spray adhesive (recommended by an LAQ for this purpose) and it gummed up a lot and sometimes would spray a solid stream or "clunk" of gunk. I had to finger smooth it out before I could place it onto my quilt.
The second problem was that (OK - call me DUMB) I was using it on flanel. Yeah, yeah, I know. Not one of my brightest moments.
