Not all the blocks in the Solstice Challenge have been new blocks but this one is! I have never heard of this block before. Tide Pool looks to me to be a quarter Log Cabin variation to me.
This block was super fast and fun to put together and I really enjoyed making it. I could see a whole quilt made out of these blocks, for sure.
Linking up for Slow Sunday Stitching, Monday Making, and more!
