This ingenious design featured in Family Fun Magazine in 2007 will work with half gallon milk cartons or juice cartons that have the spout and cap. I've gotten to the point that I will buy a particular brand (carton graphics) because I know it will make a great wallet!

Step 1: How to Repurpose a Milk Carton to Make a Wallet
You will need:
- A rinsed milk carton
- Scribe or awl
- Straight edge/Metal ruler
- Exacto knife
Step 2: Trace the Template
Trace the template on the back of the milk carton. Make sure to line up the spout hole. Make marks where the dotted lines meet the edge of the template.
Step 3: Score the Dotted Lines
Using a straight edge and an awl or a scribe tool, score the horizontal line that bisects the two half circles. Then score the other dotted lines.
Step 4: Cut Out Circle
Using a craft knife carefully cut out the lower circle.
Step 5: Cut Out Milk Carton
Cut along the solid outside lines.
Step 6: Fold Scored Lines
Carefully fold the half circles like a fan. It's a little tricky near the spout hole because you have to compete with the original folds of the milk carton.
Step 7: Fold Over
Fold over the flap and line up the cut out hole with the spout hole. If you have trouble screwing on the cap you may need to cut/make the hole a little bigger.
