Making large-scale prints for your wall can be a very expensive endeavor, but Elsie at A Beautiful Mess discovered a way to blow up her favorite photos (we're talkin' poster size) on the cheap: black and white engineer prints, also known as draft prints or blueprint copies.

The prints aren't perfect, but for prices ranging from $0.75 per square foot to $4.99 per print at places like FedEx Kinko's and Staples, one shouldn't expect them to be. For the right image, that grainy, streaky, vintage-looking print might be just the look and feel you're going for.

I think these work especially well with old family photos that already have that time-worn appearance.
