So for this tutorial I have a 12x12 paper and a 11.5x11.5 paper.
Start by folding the paper in half one way.
Unfold it and fold the other way. Make sure to crease the folds well before unfolding.
Now with the design you want to show facing down, fold the corners into the fold creases you made.
Until it looks like this.
Then fold the sides into the middle.
And then the top and bottom into the middle.
Now, unfold the last few folds you made until you get it looking like this. With the corners of the top and bottom unfolded.
Now, you going to fold the corners labeled "A" into the spot labeled "B".
It should look something like this. Then fold the point down into the box.
To look like this.
Do the same with the other side and you'll end up with this.
Make a bottom, put them together, tie on a ribbon and a label and you have a cute, easy, inexpensive box for a gift!
