I recently experimented with West System Epoxy that I tinted with Dark Walnut TransTint. I had a piece of walnut that had a knotty spot separating from the rest of the board. I didn't want to scrap it and thought it would make a good charcuterie board. I didn't get all of the air bubbles out, but for my first time ever using it I think it worked well to save the board and I like the appearance. I threw in a butterfly because I'd never done one and wanted to try it.
