I rolled my futon into the World's Biggest Burrito and then wrapped it with movers' clingwrap. After much swearing (for said futon has no easy way to grab onto it - no handles, no nothin' - I got it outside and to the car where it promptly failed to fit into the trunk. After staring at the car for a while, I noticed that the passenger door entry is bigger. (Master of the Obvious, that's me.) While better, the futon was still too big; the clingwrap kept on stretching. After much scraping of fingers and thinking of Snausages, ye olde 500lb paraline corde was pressed into service to bind the thing down where it could be scraped and cajoled into the car. It's too big to fit all the way in, so I got to drive down the street with my right rear passenger door sticking open a foot or two.
Boy, did that suck. I think I'm going to get me a smaller futon so that I don't have to put up with this again.
