It is possible to piece this using only square and half-square triangles.
There are a lot of unnecessary seams.
First I'll join the nine blocks in the center to form a large Nine Patch. Then I'll form strips from the other blocks and use them as if I were making a large Log Cabin.
This makes it easy to keep track of what I'm doing and to match seams.
