A good fire reflector maximizes heat retention and minimizes fire wood usage. Also may deflect wind while sleeping. Kudos to the builder. I have a couple of references to fire reflectors in my novel "Obliterated-Would You Know How to Survive?
Outdoor weaving, so cool - weaving is so much more than wool, or silk or those fibers that we buy at our favorite knitting shop. Fiber can be, and is, found everywhere . I love this outdoor weaving with wonderful fibers found in nature!
