Years ago, a woman who makes costumes for (Appaloosa) Native Costume classes made me a crystal/beaded brown band; eagle feather design on a pale green background with abstract native designs between the eagle feathers. The beads are faceted and sparkle in the sun. It’s lovely. I supplied the browband and she did the design. She only charged me $25 dollars, but noted that she had thought because it was small, it would be less work. In truth it was MORE work because it was small. She said if anyone else wanted one, it would be $75 to $125. LOL
I had a brown saddle for years, but it didn’t fit my “new” horse some years back and couldn’t be refitted to him. My new saddle, a Dresch, is also “brown” but it’s such a dark brown that it looks black and I used a black bridle with it. It’s an old Steubben with a silver inset on the browband, so not much bling. But I do LIKE (tasteful) bling. I still ride an Appy, so since my horse has his own “bling” without any additions, I try to color coordinate and keep it “not too much.” But heck, if you have a “plain bay” or the like, I say Go For It!!!
