O.K, so want to try and make a longer rain fly for my Clark NA and a diamond for my DD I just got. I am not a sewing guy but my wife can do some if I do the cutting and research. I saw some talk about making your own silnylon material from buying stuff at wal-mart so I headed over there. Got there and found 4 rolls of stuff that resembles ripstop nylon. 2 rolls of 60" wide greyish color stuff, one roll of shiny finish greener stuff, and one roll of white stuff. All full 15 yard long rolls I guess.
It was priced $1 on the end of the rolls. wow that is cheap I am thinking so I bought all 4 rolls. I get home and show the wife and she said it was supposed to be a buck for each yard?? I have no clue, I never bought this stuff before so here is the question: what is this stuff, how can I tell if it is thick enough to use as a fly or tarp? Here is the picture of the stuff with one roll rolled out but not un-folded.
