DIY Vertical Planter Garden. Something I would do differently, or add to it, is support under each planter. I worry the weight of the dirt, water, and plants will eventually concave the planters. Adding one more piece of wood (obviously cut into proper lengths) wouldn't cost that much more for a little more security.
Pots with house numbers. This would be so easy and would look great on the front by the door. Could also be changed easily and inexpensively. Now to decide what to plant.

oooh genius repurpose! Old filing cabinet + spray paint = raised planting bed. I might add that packing peanuts make a good filler for the bottom of deep containers, then just put your potting soil on top. Makes for good drainage too.
