I was fortunate enough to get my hands a quite a few large walnut live edge pieces. Planning on doing benches, coffee tables and serving trays with them. I will probably cut out the really rough areas to make other stuff with. My question is what is a good method to fill cracks and voids? I was thinking saw dust and wood glue. Really need to make sure I get the pieces used as serving trays/charcuterie boards filled in correctly to prevent any bacteria from food getting in the cracks. You can see some cracks around and in the knots.
