Get any US 1 dollar bill,George Washington facing up, and fold the back bottom margin up (Note I said back bottom margin.It means to start at the back, and fold it's bottom margin to the front.Then flip the bill over again.).
Step 2: Assembly
Fold the bill in half from top to bottom(George Washington side facing up), but make the fold just a hair away from the bottom.
Step 3: Assembly
Fold the top half down again, but this time, bring to the bottom edge exactly.
Step 4: Assembly
Now, turn the bill over and fold the right margin down.
Step 5: Assembly
Keeping the bill George Washington side down, fold the left side as shown in the first photo.Make sure the "ONE" in one dollar is exactly half covered.
Step 6: Assembly
Flip the left side over, so the bottom-left corner of the assembly so far is a right-angle. Look at the pictures for help.
Step 7: Making the ring's shape
Follow the pictures to get it right.Be sure to follow them exactly!
Step 8: Editing
This is very critical step.Make sure it is just right, otherwise go through steps 1-7 again before going to step 9.Make sure line A is the same length as line B.
Step 9: Continue Assembly
Fold down the vertical part, and then hold it down with your thumb.
Step 10: Assembly
Fold the "1" part across the front part of the ring.Then tuck it under the vertical part.
Step 11: Final Step
Under the ring there should be a diagonal slot.Tuck that leftover piece of the vertical part into that slot.You're done!
