Oh my gosh, a fan club I can get behind!
So, I've got roughly 350 models, and most of them are Breyer.
My favorite Breyer molds include Darwin SM, the new Fjord SM, Fighting Stallion Tr, and Rivet SM!
I'm actually currently prepping for my first model horse show which will be in August. I'm so nervous and excited to see how it pans out. I've been preparing and selecting models for a few weeks and I'm SO nervous about it since there's a lot of prep left to do in the next six weeks to be ready for it. I'm also raising funds for an equine charity at said show that I'm personally involved with!
Current customs in progress:
Sandstone, an SM scale pegasus, who will be painted in a sandstone style.
PAS, PAM, PAF who will become etchies.
I'll also be showing Tolga for the first time! Made and painted by D'ArqencialFox, one of the most talented people I've ever seen:

This model is themed to the Spectacled Flying Fox, Pteropus conspicillatus! It was made for me specifically! <3
I'm really stoked to show off my custom work for the first time, though most of those models are a WIP on my desk. I kind of made the mistake of doing writing camp along with model prep.
One thing I've had trouble finding is SM-scale tack. Does anyone have recommendations? I'm not opposed to building my own but I'd need to source the hardware which is a bit of a difficult thing to do, I've noticed.
Heck, a good source for tack in general would be nice. Also, if anyone knows where one can source compatible dolls for SM scale that'd be neat, since I can't find those either. (Amazingly, I can find MM/MW scale humans easier?) I've got a really nice CL/FR and TR doll pair; I invested in a Yvonne and I'm hoping to get their hair styled professionally soon.
