1 x Window found on the roadside
4 x colonial table legs
8 x Metal Brackets
4 x wooden Dowels
28 x Screws (depth and width appropriate to brackets and depth of frame)
1. Remove hinges from the window.
2. Turn upside down and rest on a couple of crates
3. Measure up and drill a hole in the leg and corner of the table to fit the dowel. Fill hole with a bit of wood glue. Tap the dowel into place with the hammer. Attach leg to window so nice and sturdy. Repeat.
