Hard to tell from a pic. The beige one looks like it might be brushed nylon, like they used to make pj's out of. The green one could be wool. Wool will dissolve in bleach. Cut a small piece off and soak in pure bleach. If it dissolves, it's wool.
Thanks, I'll go try the green one right now. I wish one of you guys lived close and could ID in person. I'm sure a photo id is tricky.
Oh, the beige feels a little heavier than a jammy material. Perhaps a bathrobe weight since we are using sleeping clothes as measurements.
Thanks for your help!
