Is one side plain and the other side has sew foam?
I am having this same trouble too. I am making door panels with a 4" carpet on the bottom, a 12" pleat in the middle and a piece with no pleat on the top of the door panel. between the top and the middle pleat it doesnt go straight across the panel -it curves about 45* to the top of the panel. There is a piece of welt cording between the pleat and the flat piece.
What does "witness marks" mean?
Do I trim the foam away where the pleat and the flat panel meet?
So far I have the welting sewn to the flat panel and it looks great. I can just see that it is going to be a problem to sew the pleated piece to it.
