I found a new wool rug yesterday at a thrift store for $10,and I love it. It is just in time for fall, so soft and warm underfoot. I believe the the original intent for this was to be a mattress topper (?). It has large elastic bands at each corner that look like they would keep it from shifting. I would have no need for such a large mattress topper, being that we still sleep in a full size bed. Instead I spent last night running my feet over it, while our 3 dogs soundly slept.
