My guy, while he is being very very lovely right now, has a terminal diagnosis, so I have been looking around at a lot of the people who make horse hair keepsakes, just to be prepared.
I’m not so into pottery, so I can’t help for that. A lot of the memorial jewelry places seem to use that same basic metal blanks that they set the horse hair into. Enigma Horse, mentioned above, seems to have some very unique options that I haven’t seen at other online shops, I think Enigma Horse is also more expensive than a lot of other options, but that’s also because they are more unique. I’m not sure it’s in my budget, but I’d really like to get a piece from them.
I have also really liked what I’ve seen from The Treasured Horse, partially because I want my remembrance jewelry to be subtle. I don’t need hearts or horse shoe shapes. Just a simple, attractive framework for the hair works for me.
I also like some of the stuff that Spirit Horse Designs has. They are admittedly not as much to my taste, but also my best friend is literally deathly allergic to horse hair (she loves me anyway and loads up on allergy meds when we hang out - I do lots and lots and lots of laundry before hanging out with her), and Spirit Horse Designs has some resin covered jewelry, which theoretically means I can wear it around her without risking her health. Also means that it will last longer. Both of which are bonuses for me.
I haven’t ordered from any company, so I have no personal recommendations, but I do keep looking around to see what the options are.
