I have 41 black and white disappearing hourglass blocks done. All pressed and ready to sash and set into a finished top. I'm planning a top with 5 blocks x 7 blocks. The rest of the blocks will go into the back.
I also finally decided on the material for the back. I bought a solid light royal blue by American Made Brand.
That material will go nicely with the blue starry material I'm using for the binding and cornerstones.
This top and back will be fun to put together.
