I finally choose this disappearing 9-patch. The 9-patches have been assembled for at least 4 years, so it's a perfect candidate for the challenge. Every block has a red center, and will be cut into quarters. The blocks are then mixed up, and re-assembled. These are a few of the 9-patches, and a few of the quarters. You'll have to pop in a few days from now to see how it's progressing!
I'm off to link up to Melissa's site!
