I haven't yet started clue #4, but I am looking forward to trying my new 1/4" foot on those HSTs. I'm making 1/4 of the blocks to start with and if I need more to make it look right, I have enough fabric. I am making some of each clue in the week the clue comes out, so I can easily see what's what. It's fun and I'm glad I decided to give it a try.
