BTW, has anybody tried usi

BTW, has anybody tried using mylar blankets for reflectors? They’re very cheap and it seems like they might work. You can get 12 for $11.50 on Amazon, with free shipping.

I haven’t tried this, but I’m thinking you could cut them to the size you want and attach them to foamcore board or something like that to give them stiffness. I don’t know how reflective they are, and I also don’t know if you can crumple them to diffuse the reflected light, but I might order some and try this out.
