Above is what I have finished now. Colors are better in this pic. Below is what I started with: a partially pieced section and a bunch of squares, half-square triangles and four patches. What a difference all those quarter-inch seams make!
This is the block I'd planned. It's called monkey wrench, but reminds me of Snail's Trails. The churn dash block is also called monkey wrench, I think. So many names for the same (and different) blocks in quilting.
The blocks, when put together, create alternating dark and light stars. I'd added a row to one edge of my pieced section to complete the stars. Now I'll have to work around that to finish this up. Not sure the size this will end up. I'll have to make some more four patches and half-square triangles. Can't get away from those HSTs!
