You should not give up on homemade stuff specially when you cant buy it anywhere. I have been pleased with a tarp in winter.You should lose the loops and use reinforced nail holes 3" from the edges.A zippered door is not absolutly needed. Rigid poles can be used on the ends and if they are the right distance from the end all the loose tarp will come by the pole and be tight and then lifted up for entry.I use this idea on my very big tarp(24'x36')shelter.
