Kreg Pocket Hole Plugs
Most of the time pocket holes will be placed on the backside of the workpiece out of view. If the pocket hole will be in a visible location one may plug the holes with specially cut
3/8" solid wood pocket hole plugs available in various solid wood species. Plastic caps are also available for MDF and melamine.
These plugs are made from accurate dowel for a great fit, and cut to match the pocket's angle for minimal sanding.
