No... haven't done any bitty blocks. I am not great at paper piecing. I guess I just haven't done enough of it yet. I'm really slow because I don't do it often enough to really remember how it works, so I'm stopping and double checking, etc. It's not my favorite method.
I do have a paper pieced quilt in the works, but it's very simple. Just four diagonal strips per block and it comes out looking a lot like a tube quilt. It's good for learning on!
