This is a set of 10 buttons cut from an Elm tree branch. They've all been sanded smooth with the bark removed. They have various dark colors running throughout, as well as some spalting. They're 1.5" wide and 3/16" thick. I've rubbed them each with a Beeswax and Orange Oil conditioner, then sealed them with polycrylic. They're perfect as functional buttons, or to use as accent pieces on many different craft projects!
