Step 1: Materials
-8 dollar bills
Start with the back of the bill facing up and fold in half by bringing the left side to meet the right.
Now fold the bill in half so that the top meets the bottom. Orient the bill as shows in the picture.
Fold the bottom left corner up to meet the top edge. Do the same thing with the bottom right corner. Unfold.
Now reverse fold the creases you made in the last step inward. This is the trickiest part so look at the pictures if you need help.
Step 5: Make 8 Units
Repeat steps 2-4 to create 8 units in total.
Step 6: Link 'em Together
Insert one bill into another by opening the flaps on the left one and putting the right one inside. Follow the picture for proper alignment.
Tuck the flaps from the left bill into the opening of the one on the right. Tuck the flaps of the right bill into the one on the left. This will link the two units to each other.
Continue connecting units until the entire ring is formed. Now have from throwing about $8!
