This was inspired by Truemirrors Altoids Tin mini watercolor paintbox. I wanted a very small travel watercolor kit to go with my moleskine pad.

Step 1: Paintbox in Altoids Small Tin

Following Truemirrors directions, I made an Altoids small tin into a paint box. I could only fit 6 colors. There is room in the larger tin for a small tube, so that gives me 7 colors.

Step 2: All Together

Here is the tin all together. It contains:
Paint
Paintbrush
Extra tube of paint
Pencil w/eraser
Pencil Sharpener
Water in a Japanese bento box container for sauce
Paper towel on the bottom.
