We have a couch w/ attached pillows (4) and 2 cushions. LO has managed to draw on it with pen and I can't get it out. Of course, the cover is attached so I can't wash it. I'd like to slipcover it so it'll cover the pen plus it'll give it a flesh that I can actually throw in the washer.

Any idea where I can find a slipcover for a couch like mine?
