I don't blame your for not buying that saddle. That's just too much, but im sure I would have fallen in love with it too.
I've actually been thinking about doing the same to my saddle. I've been looking at some conchos and stuff to deck out my saddle. I have a Billy Cook and it's just so plain.
I love blingy things on my greys.
You should totally do that to your saddle, I like your saddle and I think it would look good. Have you thought about where you are going to buy conchos from? I have been looking at the people and facebook that custom make them, for example Deuces Wild is my favorite tack maker on facebook. I love her conchos!
