1. To start, use the nail gun to secure the top and bottom pieces, nailing through the boards and into the window frame (figure A).
2. Take your measurements for the length of the side pieces and make the cuts, again, using the chop saw (figure B).
3. Add nails to the first side piece.
4. After securing the second piece in the first window, continue until you've finished all the window jambs (figure C).
