Another method worth trying is this stretchy long tail method This one is not as neat looking but is much more stretchy. I used a 4.50mm needle and a 2.75mm one for this cast on sample.

Yet another is called very stretchy cast on and I think that with a bit of practise would be a really good method.
OK .. having tried all three methods, THIS is now my favourite - although I do like the look of that first one. As the name implies, this one is very stretchy, and actually quite easy to do once you get the hang of it. Its a quick method when mastered as you're casting on two stitches at a time.

Whew, after all that research, I think I need a drink. Must now go and brew a fresh pot of coffee.
