Haha! Don't worry, you're not alone!
I have a horse painting on the wall near my bathroom, a wooden carving of a horse head and a pic of Charmer on my desk, and I have MOST of my show ribbons above my bed :)
I have pictures of horses out of magazines and then horses I ride/have ridden all over my walls. Then I have a bunch of horse stuffed animals on my bed that people give me. And then my ribbons make almost a border around my room. Sadly, not enough room for an actual tack space. that's at the barn.
My bedroom really isn't horsey anymore. A couple years ago I had posters ALL OVER my walls. But then I started to feel that they looked tacky so I took them all down. I had a picture of some horses but after we just redid my bedroom I'm not putting it back up. It was like an older picture and didn't fit the room. I have 3 horse plates that I'm putting back up on my walls.
Once I get some really really good pictures of Ruby I'm going to put 3 of them up in my bedroom. But I don't really want a horsey bedroom anymore.
Get this. I had a very used horse halter hanging in my bedroom for 5 years. Maybe 6. It was my first horse's halter. Ha. I always forgot it was there so I never took it down. But now it's down. Lol.
I also used to have all my ribbons all over the place. But I took them down too. Now they're in a box collecting dust. Haha.
