If I was to do it again I think I would get a circular plate because the corners were REALLY hard (notice all the glue gobs), it's a little big (4" diameter was the smallest I could find), and I would make it taller, but each box was $9! (and I used up two). All in all though, I think it's pretty cool, and now Chris has a (very) sturdy pencil holder.
Our garden has gotten quite big now! It's really nice having something done, and something that we can enjoy so much. I'm so glad we built it, it looks great, and everything tastes so yummy!!!
