The table is constructed from a piece of plywood cut to 23" x 47". From a 2" x 2" x 8" pine board, cut two boards at 21 1/2" for the sides, and two boards at 47". Apply wood glue to the edges of the plywood and secure the boards with 1 5/8" screws.
Lightly sand wood putty to make an even surface. Prime all parts of the table, but try to avoid getting paint on the piano hinge. When primer is dry, paint your table the desired color. For the best protection against spills, use semigloss or full-gloss paint.
