What is a Chalk Line?
Whether you’re hanging wall paper or laying wood floors, a chalk line is one of the most useful carpentry tools available. Sometimes called chalk boxes, these simple gadgets make it easy to create perfectly straight lines in a manner of minutes. Most chalk lines are filled with blue chalk for general purpose use, but other colors available include red, white, and florescent yellow. Red is a good choice for working outside, since the darker pigment will last longer than other chalk colors. White is easy to remove on fragile surfaces. Some carpenters simply prefer the high visibility of florescent chalk.
