I started making whoppie slings with yarn needles from Walmart. I did the taper just like the picture at this link. http://www.hammockforums.net/forum/s...ht=yarn+needle
The only little bit that has been tough was pulling the needle out at the other end. I often grabbed it with a pair of pliers. (metal needles)
I now use the loop turner and find them even easier. Can you explain what you are doing // where you are getting hung up?
Oh, I also have used this spread sheet for calculations when I did the markings on the rope to http://www.hammockforums.net/forum/s...ad.php?t=29803
