I have so small house to design tarp, it's hard to try with plastic sheet.
So i need little help. Picture is what i think. 2 same size piece sew together (red line). Result is same shape as "five yards to superultralight" tarp.
Size should be 1,5 persons. Luxury for one, possible for two.
Any dimensions to give?
ps. My house is 22,5 m2 (27 square yard)
