Hi. I'm trying to make a door like in Samaya 2.5 tent (basically a sideways "U") . With a #5 ykk uretek zipper. The problem is the curve. No matter what radius for the curve I use (tried 5-15 inch) zipper still looks deformed. I've tried using double sided tape, heat, adding a tight stitch row on one side of zipper to add a curve. The only thing that helped is adding tension release cuts. But visually it looks rough from the inside.

Maybe someone knows how it's done?
