I could post photos all day but someone needs to fix my dinner. That would be me.
I bought this CD rack at a local thrift store (?$2.50?) and then found clay pots that fit in without falling out.
Eventually it filled up beautifully with the ornamental sweet potato vines and later I changed it to purslane for a brighter color spot. I had to toss it recently (rotted) but it held up for 3 years outdoors, 2 of which was in the sun and not on the patio.
