Today I was sewing a satin lace on them. I pinned the edge before sewing.
I tried what I'd seen at a dressmaker when she was making my dress. I took the edge, folded it and fixed with an iron. It's fast and comfortable - and similar to sewing. You lay the iron and as you're moving it left, you're folding with your left hand. What's more, you gain a nice, continuous line. And save some seventy pins :-P You just have to be careful not to burn your fingers with steam.
The first piece. Ironing repaires many wrinkles so that it looks like nicely sewn:-P
