I consulted my Modern Blocks: 99 Quilt Blocks book and found about 10 that I liked for this project. I got it down to one. The Pogo Stick!
Perhaps I should have noticed before the second block that my needle was not set at 1/4 of an inch. Oops. I kept going. I ended up with four slightly rectangular blocks and blocks slightly smaller than they should be. I sashed them to make the quilt bigger. The finished quilt measures 23 1/4 x 24 1/4.
