The fasturn thing is where I got the idea, but I had a set, used by my students, and they pulled the plastic handles off them. I decided they were too expensive to get another set.
Straws (the big ones) work for tiny turnings. I can usually find something to use for other sizes. But if the piece isn't very long, a string works just fine. I especially like this method for spaghetti straps, and for things that need to be corded. In this case, a length of string double that desired is used. The middle point of the string is sewn to the right side of the piece, then pulled after sewing.
A safety pin works if both ends are open.
