Vertical wire is another great option for a garden trellis. Attach sticks on either end to stake into the ground and put on the edge of whichever plants need a little help. If you have a privacy fence in your backyard, this idea will spruce up the space where your garden is. (via Dreaming Gardens)
Inspiration: Awning using room dividers? (hmm, outdoor paint, cheap 4x8 mdf or ??, a stencil & jigsaw perhaps) ***ETA: If you like this look, but don't want the work, check out vinyl lattice panels from Acurio Latticeworks, also smaller sizes available @ Home Depot ~ I'm going to use one to make an Entryway Gate!
