Old Screen Doors
Old screen door in garden fenced in area. - cool. plus that area could also accommodate the greenhouse - no maybe not don't like the fact of the greenhouse being fenced in, but the door is great and the surrounding trestles, hmmmm?
Great idea to re-purpose an old screen door. This would also look great in an outdoor living space.
Red Screen Door Trellis (The red is striking against the white wall. Wood screen doors are still pretty cheap to buy. Wood trim from a big-box hardware store could add detail to the plain screen door. Then all you need is paint!)
