Several months ago I joined the Block of the Month at the Cabbage Rose. This seemed like a good way to try some challenging patterns. Letting someone else choose the fabrics also appealed to me. I just use whatever fabric they send me. So at least that part is stress-free.
I've completed 4 blocks and each one had it's difficulties. Only one of the blocks is perfectly square but the other 3 aren't off by much. There is no need to dwell on that though. I wanted to be challenged and I certainly have been.
