Before: old accoustic tile ceiling, water-stained paneling, horrific beeblie-bob plastic chandelier. Chandelier gone to Goodwill and replaced with a nice ceiling fan. Accoustic tile ripped out and replaced with bead board.
Paneling primed (got to get in those groves) and painted.
Cats dig drop cloths.
End product: cheerful yellow walls with clean white ceiling. Lots of texture with the bead board and paneling.
