I know there were some in the catalog that sells all items for $14.99 - can not find mine or remember name. But I found this with a search. Boy and girl swimmer pot holder among other boy girl ones http://www.flowerpotheaven.com/netshops/plantstands/Plant_Stands+zx+Metal/0.html

Hm...wondering if you could rig some wire basket planters designed for deck rails & make them work. Maybe attach L-brackets with the long part anchored under the rock. Necessity is the mother of invention, yeah. Might just try this myself. A bit OT & not what you're looking for but I've used pvc pipe to build a couple of plant stands when a crate wasn't quite tall enough & 2 were too tall. Filled them w/pea gravel for stability. Worked well as I could cut the pvc to my own specs & it left more room for my fishies to swim as my puddle is small. blessings, ~digger

Easy. Honey, where did you get those pot holders? Because Harry wants a set for his wife / I think we should get the matching apron / ninjas from space are going to beat me up unless I give them a rooster pot holder. With any luck, she stops by the store and picks up another set for Harry or the ninjas. Then you replace the burnt one, hide the others away for when you burn the next one, and brief Harry on what he just gave Marge. Of course, don't blame me if this tissue of lies collapses and you find yourself writing support checks from your sad bachelor pad.

What a cute idea! I keep my plants outside all year (I'm in south FL) so they just get pushed on shelves and "wheeled" around into the sunlight. But if I were going to keep plants indoors, I would definitely copy something like you have done. It makes a very attractive display whil still allowing you to use good quality pots that can be lifted, drained and emptied. Nice job.
