I took out Anne-Maj Ling's "Two-End Knitting" book again and managed to figure out the cast-on. I'm working on a cap--will post a closer photo once I'm further along. Trying to find people who have worked this technique before, so I can see if I'm doing it correctly. I plan to take it to Camp next week and hopefully can get some advice then. Winding the colors together, with one pulling from the center and the other pulling from the outside, definitley helps--I tried knitting along without doing that and finally gave up. It's quite fun to watch the ball untwist!
