I like sw style decorations too. Cow skulls & horns are cool.
I have a straw hat cowboy hat I picked up at a thrift store a few years ago which i've never really worn. It hangs above my doorway to remind me where I would like to be, which isn't here in the midwest I used to wear cowboy hats a lot in my late teens, early twenties.
They are worn around here by a lot of the Hispanic community around here who migrated from the sw to here.
And of course I have all kinds of cups & mugs which have anything to do with the west, AZ, NM, CO, etc. If it's a travel mug with landscaping on it I buy it.
I collect old & new kerosene lamps, don't know if that qualifies as sw but country for sure.
Plates too. (Decorative), the kind that hang on the wall. Have some from NM, MT so far.
I like sw style blankets too, along with the Native American stuff. I picked up a huge candle of a Native American indian Chief that looks cool. I think it's about a foot high. After I clean all this junk out of here I will have to find a suitable display spot for it.
