You can make a cool Cash Register Receipt Wallet to remind you to mend your consumery ways (or remind you of all the money you've spent.)

This instructable shows 2 variations on making the wallet:
1) Flat weave and fold, tape into shape
2) Wrap weave or basket weave into shape by wrapping strips around the bend and tucking them in.

The Receipt Wallet helps you fight puchasing whims with whimsy.

I made the receipt wallet with my uncle (Woodenbikes). I made this because I didn't want to spend a lot of money on a wallet. I decited on receipts because I realized that they are usually not recycled.

Step 1: Aquire Lots of Receipts

Take lots of little trips to the store to buy:
Things you thought you needed or
Things that advertisements told you to buy, or
Things you thought would help your self esteem, etc
Basically just be an American! (consumer)
We are Consumers now. We used to be Citizens.

Alternatively: Ask the nice checkout person if you can have a bag of old receipts.
Make sure they do not think you are holding up the store.

Step 2: Fold the Receipts Into 1/4 Wide Strips

Fold them in half. I like print side out.
Fold each edge into the middle.
Crease.
Now you have a 1/4 wide strip.
Crease and Repeat

Wallet is 10 strips long and 4 strips tall with 2 strips needed for edge piping. (16 qty 8" to 13" strips)
Optional Card pocket is 5 strips long by 3 strips tall (8 qty 5" to 6" strips)

If you are going to fold lots of them (like for making a receipt shopping bag) you may want to make a folder aligner out of a manila folder. You just position one edge of the reciept into the bottom crease of the manila folder and then bend the receipt to align the second edge down into the folder's crease then crease the receipt. You have used the folder (noun) as a folder (verb).
This makes very neat folded strips with parallel edges.

Step 3: Weaving Time

Flat Weave Wallet:
Take the strips of receipts like them up so that you have 10 (the legnth of your final wallet) receipts. Make sure these receipts are long enough to have eight receipts weaved into them.
Take the strips of receipts and weave them into each other.
When I do this I tape them with scotch tape so that they will be tight and easy to manage.
Keep weaving strips into the strips until you have a 10 x 8 rectangle.

Step 4: Weaving Card Pocket

Card pocket is woven separately and taped onto wallet. The card pocket that I made was 5 receipts x 3 receipts.
The ends of the flat weave wallet will be taped closed also.

Step 5: Tape Up the Flat Weave Sections

Tape up card holder and ends of wallet.

Step 6: New Technique: Basket Weave Wallet

Instead of flat, this one is woven in wallet shape like a basket.

Step 7: Basket Weave

Woven in wallet shape (not flat)
Start with 8 long strips (8-10") and 10 medium strips (6-7").
Fold the medium strips in half. They become the "ribs" of the wallet "boat".
The long strips become the "planks" of the wallet "boat".

Step 8: Lay the Keel

Not really, we have 2 lower planks

Step 9: Build Up

Keep weaving and holding things with clamps, clothes pins paper clips or tiny tapes.
Wrap strips around ends and tuck into other strips. Then tape with tiny tape.

Step 10: Weave in the 3 Strip by 5 Strip Card Pocket

To make a classy card holder, weave in the 5 strips along one side of the bottom edge of the wallet. We start them by tucking the strips behind other strips.
Add the 3 horizontal strips by tucking their ends in behind other strips also.
Later we apply carton packing tape around the whole outside surface that binds the pocket to the wallet strips.

Step 11: Piping

Piping (a receipt folded in thirds and then in half) is added to reinforce the upper edge of wallets.
Then the protective layer of carton packing tape is applied over the outside. Inside can be left bare or taped also.
