This box made from two bills. The bills/box can be the gift itself, but it is also just about the right size for a ring box. (Perhaps a dollar-bill ring?)
Get yourself two fairly new, crisp bills. Older "soggier" bills are much harder to work with. For this design to work, the folds should be very precise, and perpendicular to the edges of the bill if the resulting is to be retangular.
Lay the bill on a flat surface, face up. Fold the bill in thirds
lengthwise as shown. Gently unfold these folds, you will reuse them
later. I will refer to these as the third folds.
Fold the note top-to-bottom just to the right of the portrait, then
unfold. Repeat just to the left of the portrait. I will refer to these
as the portrait folds. Note that the third folds the oppose
(are perpendicular to) the portrait folds.
Starting at the top left corner (as illustrated), close the top
third fold to about 90 degrees. Lift the right edge of the
bill to the right of the right portrait fold up while holding
the top third fold in place, allowing the third fold
to close completely to the right of this corner.
Inside this corner will be a remaining portion that you will crease
along the natural 45 degree line to complete the corner.
Complete the previous step for the other three corners. Now you will
have two "tabs" sticking up on the left and right sides.
For each tab, pull it inside the box, folding so that the natural
edge of the box is pulled slightly over inside the fold.
(Look carefully at the bottom left of the picture.)
Do this evenly for both tabs.
For the two other sides, evenly fold over the edge of the bill.
You should now have an open box.
If you make another piece just like the first, but slightly
larger, you would have a lid similar to that found on most shoe
boxes. To adjust the instructions above, you would fold so that the
inner rectangle (bounded by the third and portrait
folds) is slightly larger.
I do not like the way that looks, so I close the box another way
as illustrated below. Try both - choose whichever you prefer.
Fold the second bill lengthwise so that the width matches the
widest portion of the open box you just made. I will refer to this
bill as the cover, and the previous piece made as the open
box in the following steps.
You need two folds as shown to be able to follow the last
step (see below). For general appearance, it is nice if these are
nearly symetrical as shown. These will be called the width
Holding one end of the cover across the bottom of the open box, find
the point which matches the corner of the open box and fold at that
After folding, open the fold to 90 degress, hold the cover
back in place, and find the point for the next corner of the open
box as the cover wraps around.
Repeat this process until the cover wraps over itself (four folds).
These will be called the wrapping folds.
There is now one very long side to the cover. Fold back the long
side so that is just a bit shorter than the first side.
I will call this the end cover fold.
In this illustration, the end cover fold is at the left edge
of the picture. I have also (gently) completely unfolded the cover,
refolded the end cover fold, the width folds, then the wrapping
folds in that order. (This unfolding/refolding is optional, but
makes the cover look nicer.)
In either case, the end cover fold puts the remainder of the long
side inside the wrapping folds. Refold the wrapping folds holding
the long side in place to crease it at the correct points.
Open up the width folds slightly on the open end, and insert the last
side under the width folds. (Normally I do this with the open box
already inside, but for clarity, the picture shows this without the
Slide the open box inside the cover before closing the cover tightly,
or close the cover with the open box already inside. In either case
you are done.
Of course if the gift box is for something special, a little ribbon
adds a nice touch. (I used ordinary curling ribbon, cut in thirds
lengthwise for this picture.)
