When I was designing my baby’s nursery, I decided on a geometric design on one wall. Three triangles in different colors, and I wanted my lines clean and perfect. Fortunately I had my mom’s assistance with the project, and being the seasoned painter she is, she had one of these aluminum chalk reels with her.
