I am wanting to use a general use tarp for my hammock so that I can play with ground tarp configurations. I was curious what y'all thought about this. I am thinking of getting a bigger tarp that I can configure in a hex patern for general hanging and pop out some doors on it when I feel like it. Most of the four season tarps I hae seen are either 10x11 or 10x12. But allot of hex tarps are somewhat smaller than that and 10x10 seems to be an ideal ground tarp size and shape. So I am deliberating between a 10x10 or a 10x12 tarp. Do I need the extra two feet and the rectangular shape to pull off the doors on the winter tarp, or will a 10x10 work just as well? I'm also looking at color. Black or navy would be best for my home here in texas but I'm wondering if purple would work just as well....I like purple.
