Sunday Fun Day: Repurposing

I'm pretty sure repurposing has become my biggest take away from Pinterest. Every time I use up something, I wonder what I can do with its container. I wonder... how can I make my storage situation easier? How can I maximize space?

Like this. The container from my protein shake mix. It's a large container, seems like it could be used for SOMETHING.

Like storing Crystal Light packets. 

All those containers were taking up THAT MUCH space. But I found something else to put them in and they take up so much less space (and don't fall all over in the cabinet).

So now, I have all of those nice containers that I can use for something else! Pinspiration coming up: http://pinterest.com/pin/185210603398451042/

What repurposing ideas do you have?
