Here's an idea. I'm not sure if it's an original one, but since I just thought it up, it feels original to me.
I am working on a small project at the moment, and didn't want to use unwieldy long needles, so I used a couple of those Clover point protectors to turn my 8-inch DPN's into small knitting needles. In lieu of buying these, you could use two rubber bands wound around one end. It sure has made this project easier to handle and I don't worry about the stitches falling off the end.
