The few friends of mine who have been able to afford Persian rugs always have them on the floor but recently I went to visit a friend's grandmother with him and she had a rather nice rug (I'm not sure if it's Persian or not) hanging from her wall. I noticed it immediately but didn't bring it up for fear it might offend her. Likewise, my friend can be sensitive about his Russian heritage so I didn't want to prod him about it but I assumed the idea of hanging nice carpets from the wall like a tapestry had to be a cultural thing. I found this article while curiously searching this morning:
My question is whether it's true that Russian families began the trend of hanging carpets as a means of keeping warm during the winter?
