The fabric sample from Cindy arrived today and I have been playing with it.
warp face is pure silk. It’s totally disintegrated in bleach in less than 10 minutes;) The warp weft. I’m not quite sure. It appears burnt (has gone golden brown) so I’ll do a proper burn test once the gas heater is on. Using tongs, a bowl of water and a metal plate as safety precautions.
I still need to test to see how it will hold up to cutting out sections and turning them under.
