I saw the forum post about the secret stashes
. It inspired me to make my own. My favorite was the map that slid money out. I messed around a little and soon came up with my own version. This can be modified for any poster.
Here's a video of it in action.
Step 1: Materials
For this you will need:
Something that doesn't look out of place on the poster (I used a trading card)
Cut cardstock in half. It doesn't have to be perfect, but close enough. Cut one half in half again and set the other aside.
Step 3: Cut Poster
Make a slot in the poster wide enough to slip one of the quarter pieces inside. Try to be neat.
Step 4: Add Back Guard
This piece wil make sure your money/whatever-secret-item-you-want comes out.
Tape one of the quarter pieces over the slit on the back. Only tape one side for now.
Step 5: Tape
Tape the other quarter piece to the half sheet at the top.
Step 6: Cut
Take the side of the half sheet that is not taped and cut it in thirds. Once again, it doesn't half to be exact, just fairly neat.
Step 7: Tape Again
This step is a little tricky. You need to tape the bottom half of the poster to the quarter sheet that acts as the guard.
This ensures that your item comes out smoothly.
Step 8: Wrap It Up...
Insert the quarter sheet taped to the half sheet into the slot. make sure it can come out smoothly. Then retract it so that you cannot see it from the front.
Make a slit about an inch from the bottom of the cardstock, but make it so that only the middle third can be in it.
Once you have done that, Put the middle third into the slit. It needs to stick out about an inch.
Step 9: Tape, for the Last Time
Tape both of the remaining thirds to the poster. This ensures the slip pops back into place when you are doneusing it.
Step 10: Test and Finish
Test it out to make sure it all works, then add the trading card, post-it note, tab, et cetra to the trigger.
