The sawdust trick isn't bad. I've found it is better to mix sawdust and glue into a slurry. Apply with a putty knife and scrape off excess. For air sucking wounds clamp a chunk of scrap into the wound (glue generously) and apply clamps. After 24 hours, unclamp, plane and sand smooth up to 220 grit. The wood can be stained to match skin tone if need be.
