Rockler Woodworking and Hardware's new State Park Signmaking Template Kits interlock like puzzle pieces to keep letters aligned and properly spaced. The kits produce continuous letters with no breaks by using two-part templates for select letters, which are routed in two phases to create smooth letters with intact islands. There is also an option to tighten the space between certain letters that look too far apart when placed next to each other -- the kerning technique. The State Park Template Kits include full sets of letters and numbers as well as a brass guide bushing and detailed instructions. They come in two sizes, with the 2-1/4" kit selling for $49.99 and the 3-3/8" kit selling for $79.99.
