rolled hem on a curve???

So I made a fins top cover last night. one of my 1st experiences with non treated ripstop nylon 1.1. I found that while making a rolled hem, the fabric wanted to be folded in straight lines, but my cut was curved. I was trying to make a channel for shock cord in the hem. I found that the channel always wanted to close up with thread due to the curve of the cut and the straight of the fold, and the fact that the thread injector wants to sew in a straight line.

Im thinking that if I go with smaller portions of the hem I can get it to turn the corner. Or maybe, if I gently lift the foot and turn the fabric every 3 inches or so then my folds might sort of make darts around the corner.

Any tricks, or thoughts out there on hemming a curve?
and Is it ok to use a rolled hem as a channel?

Use a shorter than normal stitch length. That way you can negotiate curves better. The more you fold over, the harder it will be. IOW it is easier to stitch a curve folded over 1/4" than a curve folded over 1.5".

Go slow and guide the fabric with your hands as usual. Lifting the presser foot like that will give you blips in the seam line. Nothing wrong with that except appearance.

roger that

thanx rev!
