Block Lotto is doing D4P (disappearing 4 patch) blocks, in red and white this month.
You start with a basic 4-patch.
Make a cut both sides of the center line, one-inch out, both horizontally and vertically.
Rotate the middle long stripe pieces 180 degrees, and sew the block back together.
I made two in no time!
You can find a complete tutorial for these blocks here, on Sew Wonderful's blog.
