Remove all existing trim. Score the tops of the baseboards with a utility knife. This will break the paint seal and any caulking. Use a pry bar and hammer to remove the baseboards. Next, use the pry bar to remove any decorative trim near the ceiling.

Normally, the new trim job would complete after all other jobs. But in this case, the trimming work is done first so that the log lining will butt up against it. To begin the trim job, first measure the inside dimensions of the window. Measure the width and depth of the sill and the sides of the window.
Cut 1 x 6 pine trees to length, ripping to depth needed. Put the window sill into position first. Fasten with 2-1/4" nails. Attach the top sill to the window. Then attach the two sides and wrap the inside of the window.
Measure the outside dimensions of the window, then cut the 1 x 4 decorative ribbed casing on the saw. Align with window sill, leaving 1/4" reveal and nail in place.
Measure and cut the side pieces and attach them the same way. At the top, carefully line up the mitered corners and nail into place. For additional support, nail on the sides of the trim where the corners meet.
Add the door trim. First measure the length of the inside corner piece, then measure the width. Cut to length, then rip on the table saw to the correct width.
Attach the trim to the cabinet door frame with the nailer. With both sides facing up, measure the top piece, cut and nail in place. Finally, cut and nail the front door in place.
