I use a glue stick to baste my EPP pieces. I run a very thin line of glue along the outer edge of my fabric, fold it over, turn to next edge & repeat. When all sides are folded over I give the piece a quick press with the iron. The pieces stay crisply held, there is no glue to try to stitch through and popping out the papers when it’s time is easy. Been doing it this way for years.
