Thank you for the info. I will have to give it a try, it should be interesting. Thanks again!
Burn test:
If I have several pieces to test, I light a candle.
Cut a small piece of fabric - only 1/4 x 1 inch is big enough - hold it with tweezers in the flame -
If it has black smoke and/or leaves a crispy ash or sticky residue, it contains polyester, nylon, or dacron.
The residue stays HOT a lot longer than cotton or wool ash.
Cotton (and wool) burns with white smoke or no smoke, and leaves a soft ash that powders in ones fingers.
Wool has a "burn feather" smell.
Rayon is made of wood pulp - and that also burns with a soft powdery ash.[/quote]
