Headliner Dimensions and Finish

Nellie's salon headliner is made up of tongue-and-groove boards that are 1-13/16" wide and ?" thick. The wood used, Laban, is clear grained and light in color. Maple is a close grain substitute. Semigloss is the best match for the finish.  (Update: According to Tommy Chen the headliner's luster is a result of mixing semigloss and gloss finishes.)
