I've been looking for something very well made and hopefully long-lasting for orchid mounts. I found this vendor on ebay who hand-makes wooden orchid mounts and baskets. I received them this week, and I must say they are GORGEOUS!!! I'm rather picky about stuff, and he definitely will be getting another order from me.
check him out!

They are pricier than the ones you can buy at a store, but I think they will last longer. They are simply really well-made.
