I made the block just to see if I could. I think it turned out pretty good considering I switched machines half way through making it. I used a generous 1/8" seam allowance. I switched machines cause the second machine had a foot that gave me a better view of the needle and where it was going.
I didn't really doubt that I could make the 3" block with set-ins. But the other day at the Crazy Quilters show in Mukwonago I was talking with author Marie Bostwick of the Cobbled Court Series. I met her in Nebraska when we were both guests there for a quilt conference. She said the thing she remembered about me was that I said I would have no problems doing a 3" star with set-ins. I guess I remember that conversation a little differently than she did. So when I found I had a few minutes this morning with a tiny bit of scraps I thought I'd give it a go. And guess what? No problem. Imagine that.
I've got no plans to make more though I do think those little blocks are darn cute. It took such little bits of fabric the size I often toss in the trash. Ouch. Just think of all the little blocks I could make with the trash. Do I dare see how frugal I can be and . . .
