Coffee Cans FTW!

Peanut butter jars are great - you nail/screw the lid to the bottom of a cupboard, and put something in it.

Babyfood jars and small glass (matching) jars with metal lids are great as well, you can use them in the kitchen to organize bits of spices and such.

Beer bottles - Clean them up good, like you're going to take them back to the distributor for your deposit - but instead, let it dry, twist a cap back on that has 4 or 5 holes drilled in it (salt/pepper shaker)

cardboard beer can/soda can cases - make awesome material for making templates and mock-ups, easy to manipulate, easy to cut, free if you mess up.

And here's today's longshot reuse:

If you have a can of peanut butter that sits in the heat for too long, it may separate partially, and you'll end up with oil on the top.

First of all - don't throw it away, it just became slightly healthier for you.

Second of all - drain that oil into a container. The next time you're polishing your car, and you notice the graying rubber trim on your car, remember where you put that peanut oil - it will recondition the rubber and make it black again!
