Pamela thank you for the great block, love the colors in your fabric choices!
Libster love the chevron star of delight quilt block!
As for cutting errors I had mine last year, the second time I was involved in a Boom swap. Your heart sinks when you realize your mistake, then comes lots of choice words. The real challenge is being to create something out of that mistake and the self satisfaction of completing that "oops" block.
