Oh, that's good to know. I suck at anything that requires carrying a yarn from place to place. I think Fair Isle requires carrying the resting yarn from one place to another so it's ready to be used at another site.
Intarsia, I can do. I think that's just dropping one color and picking up another, using the 'wrap' to prevent holes, and picking up another color. But if it ever required 'carrying' a yarn in the back of the work (stranding)......not my bag!
