I have been scouring the wally worlds and fabric shops for Sil Nylon and ripstop, and I scored big today at wally world. Only issue is it was cut in 3 yds increments, some 2 yds, and a few 1 yds....but at $1.05 yd, I am not complaining. Perfect earth tone colors too, for my bow hunting adventures, gray and green. My new Brother CS 6000 I computerized machine arrived yesterday, and last night, I was a sewing fool. The machine sews like a dream!! I sewed a sil nylon floor into a Sea to Summit bug bivy, that I bought on clearance. Now I have plenty of material to build several hammocks, and a huge A Frame tarp with closed ends, that will have a stove jack, so I can have a heated hammock stand up shelter. I am pretty stoked, and wanted to share my good find with you all!!
