Got some $1/yd stuff at Walmart.
Woven, shiny one side, looks like it could be used for lining, very hard to blow through, but can be done. Took it home, draped it over a measuring cup, poured some water in, and it didn't drip. I left it in maybe 30 seconds. poured the water off, it was very slightly darker on the non-shiny side that held the water, and very very slightly moist, more like misty, on the shiny side.
Is this uncoated taffeta?
Can I use it for a rain suit? Sleeping bag?
Or is this considered water-resistant/breathable?
