I think it is a good way to learn new techniques for blocks and assemblies. I don't know everything, and though I love to do my own design and calculations, I have learned a lot from following the instructions of professionals. I think it is part of growing as a quilter. Isn't that why we are part of this board - to learn and share what we know? The more you open yourself up to, the more likely you are to get better at it.
What can you learn with your head under a bucket?
