The 20" steal planters with rusty patina in the photo above were made by artist Joe Papendick. I asked him to make me some after I was poking around some of his photos and saw that he had made these cute planters pictured below.
Recently I decided to order an even bigger one for the back patio area. I've bought metal planters in the past and they feel so thin, they were never big enough and don't weather well. The planter below is from CB2 and this was the biggest size they made... not big enough. The new one will be big, 42" x 32" x 12".
I'll post a bunch of pictures when it arrives!
