Those are wonderful scrappies. I, too, have not done any fabric shopping. Just shop in the 'fabric store' in the my sewing room. I am surprised what I find there.
Wow, they are all great. You give me inspiration to do the same--only use my stash for the main blocks. I keep resolving to do that, but have had no luck so far. I will keep you 4 "Bs" in mind.
