When you're joining two boards with glue, you might get a little glue overflow along the joint. Avoid that problem with a bit of tape and a razor blade.
The Family Handyman explains:
To prevent stains caused by oozing glue along joints, clamp the pieces together without glue. Put tape on the joint, then cut along it with a sharp blade. Separate the pieces, apply the glue and clamp them together again. The glue will ooze onto the tape, not the wood. Peel off the tape before the glue dries.
It's a simple way to keep your woodworking project looking just a bit nicer. Hit the link for more woodworking tips from the Family Handyman.
