I printed the enlarged image on card stock, cut it out, and then taped it together to make a stencil. Using the stencil, I traced it onto the pickets. Next, I used my cheapo handheld jigsaw to slowly cut each picket into the shape of the state outline. After cutting all the pieces, I tacked some 1.5 inch furring strips from Lowe's (seriously, they're only $1.50 for an 8 foot section) on the back to hold them in place and made sure to add wood glue before finishing nailing them so they would hold firmly. After the glue dried, I stained it with some wood stain and let it dry. I think it turned out great!
