I like Ocean Waves - I'm making one with 1" triangles, but you can make them any size you like and it's still pretty.
Some of the HST's are two "light" fabrics or two "dark" fabrics sewn together and the rest are made of one "light" and one "dark."
Mine is from Civil War reproductions, and there wasn't as much contrast in some of the quilts from that time, so I'm being pretty random about my color choices.
If you like doing hand work, you might like to take your triangles to your tv chair and work on them. Every now and then, take a batch to the ironing board and press them and trim them to the same size square. :)
