I just redid my 12' x 20' sewing room, and painted the walls a mocha/latte color - not dark. But so much more fun than white! My pictures just 'pop' against the color. All my furniture is white, and the floor a medium brown vinyl tile.
For my large 6' window I bought a dark brown bamboo patio shade - it was only $25 at Home Depot. I'm making curtains for the small windows in teal, lime green, lt and dark browns.
Have FUN with it....it is such a pleasure to be able to decorate a room that is JUST FOR YOU :thumbup:
