Reuse - Organizer for Needles

With multiple projects going on at the same time, I often have to change the needle in my sewing machine, and wanted an easy way to keep track of them when I took them out temporarily. I found a CD case laying around unused, and it's little book-like structure with pockets is perfect for organizing needle cases and holding individual needles that still have life in them.
I slip a piece of paper in the CD pocket along with a needle to indicate it's size and how long it had been used.

And the CD case is easy to pack up and carry along, if need be.
