So I went tommy local Wally-world today hoping to pick-up some rip-stop or polyester that I could use to practice on while I am waiting for my order from "Ripstop-by-the-Roll" to come in. WW had some fabric made in China that was labeled "Promo Fabric, remnant of undetermined fiber content". It's 45 inches wide and goes for $1.50 a yard.
My guess is its polyester, I weighed it and appears to be something about 2.5 oz a square yard.
I was wondering if this stuff is worth using to make something out of. Or is it just fit for practicing with...
