If you're like me and you've got a lot of crap, you like putting stuff in boxes. Problem is shoebox manufacturers so rarely make the exact size you need.

Well, problem solved. EvilMadScientist has a pretty simple DIY tutorial on how to make those Japanese papercraft boxes in any size you need; just download the template, tweak the dimensions, and now you've got a box that will precisely fit your spare ethernet cables, postcards from your lover in Alsace or whatever unstandard-sized thing you need that must be boxed.
