finishing skylight interior

The first step in finishing the interior of a skylight is to determine what material will cover the inside of the space. Typically, the grid will be made of two or three pieces of 2-inch or 3-inch hardwood. You should choose the same type of wood for the surrounding woodwork. If the drywall is made of plywood, cut the plywood into a rectangle before sanding. Then, cut the sheets to fit.
