I just used the glue for the first time to make pillow cases. I used the glue to keep the part folded in so I could sew it down by machine instead of by hand. It worked like a charm - very thin line, then ironed the fabric to dry it - it wasn't totally dry, and if I had pulled on it, it would have come apart. It held just enough so I could sew a straight line and no pins to poke me or break in the machine. It was funny because I was making 4 pillow cases, and the first one I pinned and it was a royal pain so thought, this is it - this is the time to try the glue and it worked like a charm! I was so excited I was telling everyone that would listen. No idea how it would hold to pellon - but it was totally wonderful on cotton. The clue is ironing it to dry it.
