When I was teaching I had to make lots of creative projects like that. Once, I used a white vinyl table cloth for a large-scale drawing because it wouldn't tear like paper, traveled well and could be used again later. Sharpie permanent markers worked great.
Also, it's complicated, but if you could print a clip art picture of a fridge onto a transparency, then get access to an overhead projector (maybe at a grade school or a church in your area?), you can project the image any size you'd like and then just trace it onto the paper or tablecloth. I'm such a nerd teacher, I wish I had an overhead projector in my house. They're awesome!
