LOOK AT THIS CHAIR!My boyfriend and I were walking home the other night when we came upon this chair, which somebody had thrown out with the garbage. I was so excited when we stumbled upon it, because I've always wanted to be one of those people that has a really great piece of furniture that they just picked up off the street. The chair itself seems to be unbroken and not urine-scented (musty, yes) or otherwise stained. The only problem I can find is that it's missing its seat cushion, making it very low-to-the-ground and unable to be sat in (but as decor it's still awesome). But the cushion part is where I need advice: A) Where do I even find a cushion to fit such a chair? B) If the cushion needs to be covered, any ideas on what kind of fabric/cover to use and where to buy it? C) I was thinking that, since the upholstery is going to be nearly impossible to match, the cushion should be in a contrasting color. Any suggestions?
