When I was little, my parents bought an old "dressing table" from a junk store. My dad then cut off the center part and put a long piece of plywood across the top. I had two sets of drawers to store things in and a long work surface (8 feet long.) A little paint, the framed mirror taken off the vanity and hung on the wall flanked by two wall lamps, painting and covering an old dining chair -- voila, a perfect work area!
He took the other half of the plywood and put it on top of two old file cabinets and made a "boyish" work area for my brother.
I did everything at that "desk"--put on makeup, homework, crafts, and even practiced my flute.
