That really depends on the strength of the wire. the heavier wire would be better, but then you have a unwieldy heavy contraption that will probably have spent a fortune on. hmm...I guess another way to do it is to have collapsible camping style tent rods for the four sides, and then just make the polyester have sleeves on all four sides. That way you can put the tent poles through when you use it, and then collapse the entire thing down when you don't need it. For each corner, just have a small block of wood that has holes on 2 of the six sides that you can insert the ends of the poles into. So, to sum this contraption up:
- get 2 sets of collapsible tent poles. Cut them so that they can still collapse, but are much shorter. A hacksaw to cut the titanium, and then re-tie the ends of the elastic inner around a washer so they still collapse properly.
- Sew the four sides of the polyester into sleeves, so the tent poles can slide through the edges. By hand is cheaper, but a sewing machine would get it done in minutes instead of hours.
- get 4 small pieces of wood to act as corners. Get a drill and bit that is slightly bigger than the tent pole ends, and drill two adjacent sides half way through the wood. this will hold the four corners of the screen.
- slip the fabric over the tent poles, attach the four corners of wood, and the fabric alone should hold it pretty well. You can always have two more tent poles to act as diagonal braces, but this is overkill. personally, I love Overkill, but that is just me.
This should work pretty well, and last for a good while. the weakest part is the stitches, but a double stitch pattern would hold for years. Plus, its frugal, which Is awesome, and relatively minimalist, which always looks neat (I am a minimalist, so the less parts the better).
