In attempting to draw Kris' Red Eye Twist I goofed and came up with THIS variation. (Instead of matching Twists, I lined up the seam that falls in the middle of each block side.) I can tell you that the "Red Eye" (the block that goes into the hole created when the blocks are off-set) in THIS variation wants to be 5¼" x 5¼" but don't ask me how one is supposed to sew everything together!
