Oh, CONGRATULATIONS!! I am SOooooooooooooooo envious!
I am always stuck on "traditional" patterns, even for babies--so should I ever find myself in your enviable position, I would start churning out Clay's Choice, Log Cabin, Baby or Tumbling Blocks, Wild Goose Chase, any of the Star patterns, Grandmother's Flower Garden, there's so many beautiful options ....
Have fun and congratulations again!
