What is a Nostepinde, you ask? Well, let me tell you all I know which is really just very limited reading on the internet. I believe they are traditional wooden yarn winders that have been around for eeons, and, while they might not be as fast as a ball winder, they are a lot cheeper and really get the job done very nicely. Here's how I use the Nostepinde method with a piece of PVC pipe.
Start by holding the tail of the yarn with your thumb and fingers so it won't run away on you.
Wrap a 2" (or so) section on one end of the pipe (any dowel shape would work actually so don't feel stuck if you don't have pvc, you probably have a wooden spoon, right?). You'll be wrapping the pipe toward you and winding away from you (clockwise). When you have it well covered (maybe 1-2 layers of yarn), start winding from bottom to top on more of a diagonal. I've made a very exaggerated first wind to show what I mean. At first it won't want to go that direction and your first few diagonal winds will be rather shallow, but keep at it and it will get better.
Keep winding and winding, turning the pipe/dowel/stick... toward you as you wrap. Eventually the ball will cover all the first couple of rows of yarn and if you wind it right, you end up with a ball that is flat on top and bottom and won't go running away on you. Tuck the tail in with a crochet hook and slide the ball off the pipe. Et voila, a wonderful, center-pull ball.
