What you will need...
- Paperclips (optional)
First, you will need to cut your card in half down the fold.
Next, measure and cut slits that are approximately 1 inch from the edge of the card and 1 inch long.
Then, fold the card along the slits and glue the corners.
When the glue is drying, you can choose to firmly hold the corners for several seconds or just paper clip them until dry.
Repeat these steps for both sides of the box, and fit them together when done. Now, you have the perfect gift box, and it did not cost you a thing!
