So I'm just doing some more tiny Christmas decorating over here and figured I'd share the process as I go.
I started with the walmart wreathe ornaments with the bird.
I had some partially customized mini whinnies I was probably never going to do anything with and some fun metallic acrylic paint.
It took me about 3 coats to get the horse fully coated, might take less if you prime.
Then I glued and clamped it on. This was super easy and not only do the make excellent barn decorations, they could work just as well on a real tree.
