Are you working in the round (with circ's or dpn's) or flat?
I found flat Fair Isle difficult but my yarn didn't tangle because I followed the two handed Fair Isle method (shown on circ's in that link). I was using straight needles and working flat, so for me it was the purling on the WS that stumped me. I took the rocky road of knitting left handed to get back from the left to right (no turning to the WS.) :roll:
Either flat or round, keeping one color in each hand will stop the tangle (at least until you turn a flat work).
Good luck! Crossed Fingers
