Thanks all for your nice comments. They're not hard at all to knit. They look a little intimidating, the thing I was most concerned with was all the bobbins, but it's way better than trying to strand across those big blocks of color, and the bobbins behave themselves for the most part if I go slowly. The most important part to remember is to twist your strands of yarn when you make color changes, otherwise, you'll end up with holes and funky stitches.
The only thing I'm not totally happy about so far is that the diamonds are starting to look wider than they are tall. I was hoping for a more "square/even" looking diamond, but maybe that can be fixed during blocking. We'll see!
