I have finished steps one and three, skipping two for a while. I will make them when I am done with the center. No matter how much I check and double check seam allowances, my quilts always end up a touch on the larger size. The last few mystery quilts I did I had to add extra pieces into the borders, because the differences were too big to ease in. Think I will finish the A units all the way to the end, then start on the butterfly ones.
I seriously debated doing a simple nine patch for the butterfly unit, but I think I would run out of garnet, and I don't have any extra in my stash to supplement it with. Decisions, decisions!
