Hi,the other day I was shopping at my local thrift store and found this rug it is a very fine handmade rug I believe it to be silk but don’t know how old or where it may have been made it could also be a silk wool blend but may guess would be all silk it measures 4x6 it is in very good condition with no damage other then the fact that it needs a good cleaning any more info about this rug would be gladly appreciated also would like to know about how much would this rug cost to clean and what would this rug be worth once cleaned,lol i payed only $2.00
