I just did a test run with a $12 polyethelene woven tarp
and have decided I like that size tarp.
Campmor has a silnylon 10x12 for $90 that weighs 19oz.
I could build a 9x12 out of .65 cuben that would weigh about 10oz after reinforcing, glue etc. It would cost me about $200 to build.
Other than weight what would be the benefits of one over the other.
