You should be able to procure the materials for around ten dollars (I spent $11.50):
- Four 5 foot sections of PVC. I would recommend 3/4" or 1". These act as vertical support. Buy ten foot sections and cut them in half.
- Duct tape to bind the tops together. I suppose a more robust solution would be better, but duct tape has held up well for me.
- About 25 feet of rope
- 6x8 blue tarp
- Two tent stakes
The setup should be fairly self-explanatory. The PVC acts as a frame, with the legs angled slightly inward. The rope his held taught by the stakes, and runs through the eyelets of the top edge of the tarp.
I run the rope through the corner eyelets twice as shown. This holds the tarp tight against the frame, and keeps it from sliding away towards the middle.
I used a rubber mallet to drive plastic camping stakes into each end. It is sort of hidden in the grass, but I tied the rope to the stake with a half-hitch knot. I then tied the lose end of rope to the eyelet at the bottom of the tarp, which keeps it from floping around in the wind.
