I laid the bounding bunnies out on the floor and discovered I had an extra left bounding bunny and was missing a right bounding bunny. Obviously, one of them switched sides. So I made another pink bounding bunny.
And here are the bounding bunnies laid out on the floor. Each bunny finishes at 6 by 6.75 inches and the carrots finish at 6 inches square. And for now I'm planning on using 1.25 inch sashing, although I should probably think about the borders sooner rather than later.
And Molly says she has it on good authority that if I want people to look at my bunny blocks, I should make it interesting.
