Thanks also to Bumpus, who added a three-dimensional Kiteman more quickly than sanity allows.
I have entered it into the Workspace contest. Unfortunately, I am ineligible to win, so (if I win), I will ask the contest organisers to pass the prize over to some deserving cause within the US.
Step 1: The Net
I measured up the shed, and divided all the measurements by thirty to make the net fit on a sheet of A4. The scale is, then, 1:30 (which means that, if I emptied my shed, I could fit 27,000 of these models into the real shed).
I drew it up in CorelDraw, saved it as a PDF, then copied and pasted into Photoshop Elements to add a woodgrain effect to the appropriate panels.
The various resultant files are presented with this step. Print them out on normal paper or light card-stock.
You will also need scissors, glue, a sharp craft knife and a metal ruler.
Step 2: Construction.
You could cut out the window if you want, but I'm not adding furniture yet, so there didn't seem to be much point.
When you have cut it all out, a black marker can vastly improve the appearance of edges and joins if you draw along the cut edges.
Glue the side tabs, and stick the body of the shed together.
Glue the three top tabs, then gently but firmly press the roof down - you may need to reach in through the door with a pencil or skinny finger to press tabs against the roof.
Now, squat down level with your workspace, squint, and imagine a tiny paper Kiteman, working away inside your tiny paper shed...
