If you have an hour to spare, how about making this wooden wall planter? Whitney says it cost her less than $20 to fabricate, but I'm guessing a lot of us already have the materials on hand to make one. Leftover 2 x 4's from another project, paint, a bunch of clay pots (okay, maybe we'd have to buy those), and some rope is all it takes materials-wise. Throw in a drill, wood glue, and some finish nails and you're good to go. For the entire tutorial, head on over to Shanty 2 Chic.
