Step 1: Overview of awesomeness
This box stash is perfect! PERFECT.
Step 2: Construction Materials & Supplies
1. Sexiness, or something to hide.
2. Box, Drawer, something similar.
c. Bits of wood, etc
4. Material for false bottom
c. Paper Mache
d. Whatever else you can find.
3. Extra sexiness, just in case you've lost yours already...
Step 3: Construction of 'box' -- False Bottom
For the false bottom, you may create it out of wood, anything, just as long as it fits discreetly inside the box so nobody notices.
For my false bottom, I made panel of wood and stained it the same color as my box, which has worked quite nicely.
Step 4: Construction of 'box' -- Drilling holes
The hole you absolutely need, would be the one in the bottom to shove a pencil/pen/stick/rod/screwdriver/etc through in order to lift the false bottom.
Optional holes: In my box, I put 4 holes in the corners of the false bottom in order to prevent going against the air pressure.
Step 5: Construction of 'box' -- Supports
Use anything you can find, just make sure it's thick enough to hide whatever it is you're hiding. They also need to be of equal height, and reasonable. For example, you can't open up a 4" drawer to find an inch of space.
Another optional suggestion would be to glue your supports into place, however it's not necessarily needed, depending on your setup.
Step 7: Operation
To open, take any pencil or rod-like-object and insert it into the hole upon the bottom of your box, thus lifting your false bottom which will in turn reveal your hidden sexiness. Lift up the lid, then add, remove, or replace any objects or materials of your choice.
