I know that those are a bit heavy but I wanted something easy to work with on my first projects because I have never sewn before. I will be creating a second set of lighter tarps and hammocks after I finish the winter tarp and blackbird clone using my remaining fabric. The hammock material is surprisingly wind resistant compared to my ENO DN and it only slightly stretches even under my 280 lbs. with a single layer hammock.
