I picked up a bunch of rugs yesterday. They're all standard but this one. According to the owner, it came from Peru and is wool. I haven't had time to look at it super close yet but haven't seen one and don't even remember seeing one passed around at the rug cleaning class I took. I think it might be felted wool but can't find any posts on these. If anyone has cleaning suggestions, I'm all for them. Other wise it's going to be lots of vacuuming and hand encapping.
