When I'm woodworking, woodcarving, or even KnifeMaking, I encounter worm holes everywhere I go. And most of the time I fill it with Epoxy Resin or wood filler. Wood filler is more natural, and blends with the wood. Epoxy Resin is usually for when I decide to inlay a stone, shavings, etc. But when I do use wood filler, one helpful tip can change your woodworking forever.
If you don't have wood filler, no problem! You can simply make your own Wood filler with any color wood you like. Just simply mix Wood glue and Saw dust together, and it works just as good, if not, better than regular wood filler you buy at the hardware store.
