> I'm not really sure I would have that much condensation ??
As soon as it cools down a bit, you WILL have condensation in a Cuban Fiber shelter unless you have very good ventilation at the top. And don't even think about closing it down!
The one rule I would give aspiring shelter makers is to be paranoid about getting enough ventilation right at the top of the shelter, to let the humid air out. Sure, on a hot night in the desert it might not matter, but not all nights are hot.
Look very seriously at using sailmaker's seam-stick tapes for joining Cuban Fiber fabric, backed up by long stitches if you must - but the right tapes don't need sewing and make a much better (stronger, waterproof) join. The company can advise on the best tapes, but 3M 9485 is pretty good.
Use tapes for the reinforcing too. This stuff is NOT a woven fabric. Different thinking is needed.
