I recently received my copy of Morgen Kilbourn's Mini Hazel, and she's gorgeous. Simply stunning. The cast is beautiful, second only to the clean casts from Sarah Rose, and by just a tiny hair. If you were on the fence about it, buy one. It's a short edition of only 9 months, so you have until August! (Here's her link on Morgen's website)
Mini Hazel has me smitten, but she's a BIG girl. She's going to need her own patterns, her own tack, her own props. Morgen lists her at 1:30 scale, and there's no way she can share with some of the other large mini performance horses out there.
The larger size is going to be a challenge in some ways. I already make almost all of my hardware, so no worries there, but I think finding stirrups for her will be difficult. I'll have to draft new patterns for her and sculpt western trees in her size. It's another learning curve, but after the first one everything gets easier.
I haven't seen very many photos of her with other models, so here are a few to give you an idea of size (view the full album here: https://goo.gl/photos/yP1u6mXParmpMQSF8)
