I framed the inside of my arched cabin outside with the lattice. Since the outer wall is curved, everything has to be measured from the bottom up, so far I've made sure to use a tape measure and spirit levels. With the wall paneling, floors, countertops, and cabinets still to be installed, I decided I needed a laser for accuracy (especially on floors and cabinets) and to finish my projects faster. I had the opportunity to order this DEWALT Laser Level, Multi-Line Green Model DW089CG. All of my tools are DeWALT, so I figured the DeWALT laser would be just as good as the rest of my tools. I am not disappointed! This is a high quality laser level.
