When it comes to fixing gaps that are already there, professionals have a few tricks. They might use wood filler, or mix sawdust with glue for a perfect match, or even use thin shims made from the same type of wood veneer. When these are sanded down and finished properly, the repairs blend in so well you can barely tell they're there. Sometimes, they’ll just tap the joint gently with a mallet to nudge the wood fibers and close up those tiny gaps.

Lastly, skilled woodworkers make sure gaps don’t happen again by controlling the humidity in their workshop, always using sharp blades, and cutting all the matching pieces at once. It really comes down to precision, patience, and being well-prepared – those are the things that make professional woodworking stand out from the rest.
