I've started making Tomato, too. I love the neckline!
The 2-color knitting was a little intimidating at first. But, once I got started, it turned out to be fun. By the way, I held one color with one hand and the other with the other. So, now I'm finally able to knit English/American style -- but only if I pretend to hold yarn with my other hand as well.:lol:
I may not have really gotten the concept of Tomato. I'm making it in navy blue wool yarn with a lighter blue contrasting color. (I guess it's a tomato/blueberry hybrid.) I didn't move the stripe, but then I'm short waisted.
