This may look fancy, but it's really all based off of 8 simple folds. If there's any step you're stuck on, leave me a comment, and I'll try to help you out!
Start out with 2 sheets of computer paper. Make the largest square possible out of each one, and put everything but one square aside.
Fold the corners together, and unfold
Fold two opposite corners into the center
Then fold those folds into the center.
Do the same to the other two corners
See that group of 4 squares in the center that my fingers are outlining? That will be the bottom of the box. You can outline them in pencil if that'll help.
Fold a corner over along the "bottom" edge, and crease hard (you'll be tearing soon)
Tear these four lines, only until you reach the "bottom" square.
Fold, fold, fold.
Hold the two pointy tabs together so they form kind of one continuous side.
Then fold the long strip over, and....
...down, to secure the two pointy things.
Do the same for the other side, and then fold your other square the same way to make a lid.
Note: it doesn't really matter that the lid is the same size as the bottom-- it's paper, so most likely the lid will fit on fine (I've never had problems with that anyhow)
Make a bow!
Remember those two rectangles we have left over? Cut those each into four thin strips.
Simple loopy bow shape. Glue the ends in place.
Glue them onto the lid!
Experiment with the bow too-- the possibilities are virtually endless!
