Sanding-disc shim cuts plugs close
I like to use wooden plugs to hide screws in my projects, but tediously sanding the plugs flush with the surface around them isn't high on my list of fun things to do. Even when I saw the plugs off first, no matter how careful I am, the teeth of the saw often mar the workpiece, which means even more sanding.
I minimize both damage and sanding time by slipping a well-worn random-orbit sander disc, grit side down, over the plug, as shown below, before sawing it off. The disc protects the workpiece from the saw's teeth and leaves just the shallowest nub on the plug that sands away quickly.
