1.00 ring

2. 1
   Place the bill on a flat surface, face up. Smooth it out as much as possible.
   
   
   
   
   
   • If it’s too old and wrinkly, consider ironing it first.
     
     
3. 2
   Fold the top end down. Do it so that the fold falls just under the white edge. This covers the white edge and makes the finished ring a bit slimmer. Note that the front margins are different from the back margins!
   
   
   
4. 3
   Fold the bottom end up. Do it the same as the top fold, to cover the white edge. The exact width for these two folds isn't critical, but try to keep them parallel with the edges of the bill. 
   
   
   
5. 4
   Fold the bill in half lengthwise. Bring the top and bottom edges you created together. 
   
   
   
6. 5
   Fold the bill in half lengthwise again. Run your fingernail or a pen over the fold to make it crisp and clean.

7. 6
   Check your folds. They should look like this if you open up the end. 
   
   
   
8. 7
   Note that one of the small numbers should be facing out. Place it so that it's on your left, as shown. 
   
   
   
9. 8
   Fold the right end of the bill upwards (over itself). Form a 90-degree angle, about one-third of the total length. The placement of this fold can be adjusted to make the ring larger or smaller.
   
   
   
10. 9
    Wrap the tab around the bill. Fold it straight down behind the bill. 
    
    
    
11. 10
    Turn the folded bill over, so that it is oriented as shown. 
    
    
    
12. 11
    Make the ring. Take the long end sticking out to the right, and curl it in a loop around the back. Pass the free end under the tab that is sticking down. 
    
    
    
13. 12
    Take the short part of the bill that's sticking out behind the tab, fold it across, over the angled fold on the outside of the ring.
    
    
    
    • Arrange the number so it's on the outside, then tuck the end underneath. This is the "stone" or "top" part of the ring.
      
      
14. 13
    Fold the loose end that's still sticking down under and tuck it in under the "stone". 
    
    
    
15. 14
    Admire your good work.
    
    
    
16. 15
    Finished.
