I love the adaptability of the solution. I ended up getting 4 9-in-1's and "creating" 2 kidney-shaped gardens. I had to 'flip' two of the curves to be inside-curves and they join on the ridges, but it worked. It's also about 1 ft shorter on the long side than it is on the 'entry' side. It would be great if this was provided as an option - You would have to replace two of the curves with 'inside' curves, painted on the 'inside' and replace 2 of the 18" straight pieces with 2 24" pieces. Anyway, the difference is barely noticeable and I filled the gaps where the inside curves meet the straight panels with 'great stuff' foam to keep dirt, etc. from coming out. Then I spray-painted the inside curve gray to match the rest of it (Since the inside curves are flipped, the white is showing on the outside). Filled it with logs, leaves, clippings, organics, and dirt!

Anyway, it came out great - I am very happy with the product, delivery, and ease-of-setup.
