Another "tip". I put a point protector (I think that's what you call them) on one end of my first needle so that I could easily recognize which one to start and end with and it helped me relax and not worry about my stitches falling off while I wasn't looking.
If you don't have one, you can use anything to mark it (if you have any oldfashioned pencils around, pull the eraser off and they work great.
Also, just sort of "ignore" all the needles except the one you are working on and don't worry that you're stretching the stitches...they'll probably even out after you've worked more rows. But, when I first tried dpns I worried too much about if the other needles were up or down, over or under and got frustrated and quit...and when I ignored them and just concentrated on the one I was working on, it seemed to work.
Again, I only did it the one time...but, it worked great and I'm ready to try it again.
