# How to Make a Scarf With Nails on a Board
Scarfing is a process used when installing baseboard trim to join two pieces of trim together along a long wall. The boards are cut at a 45-degree angle and sandwiched together, rather than cut straight across. This is done to help the wood expand and contract with the weather. If the boards are cut straight across, then the wood may buckle and pull the nails away from the wall.

1
Measure the length of the trim boards that you need. Mark the area where the boards will join on each trim piece.
-
2
Cut the ends of the trim pieces with a miter saw. Cut each end at a 45-degree angle. Cut one piece opposite of the other piece, so that the angled edges align to make one solid piece.

Nail the trim pieces to the wall as normal using small finishing nails. Leave a small, one-eighth of an inch gap between the two trim pieces to allow for expansion of the wood and the shifting of the walls during normal weather changes over the seasons and years.
