I would prefer getting a simple block done well (ending up at the expected size being a prime concern) than a complex block done poorly.
I understand that we are all at different stages of our quilting lives - some of us are learning more and getting better, some of us - for whatever reason - are unable to do as well as we once did.
But I still would like the blocks to be close to the expected size.
There is always something to be learned from other people's work.
