I've been away, and haven't had time to catch up with all the posts, so, not having read most of this thread I thought I was about to say I have a unique method of knitting, only to find this message!
I, also, knit with one needle under my arm. Means I need to use long needles, and am VERY reluctant to use the 4 together, but it does make for very even knitting, and I also read and/or watch television as I don't need to watch the needles. This is one reason I don't enjoy crochet - need to keep my eyes on the work.
