I've been nose-down in the recycle bin at school, looking for copy room mistakes: card stock printed inappropriately (Why didn't the person who used the machine before remove the cs from the bin?!) or stuff that printed with the lid open (pure black). Totally not archival, but usable. Sheri, we could market our ideas, but anyone who'd be interested would be too cheap to buy 'em!
Have fun! with Love,
