I made a whole batch of these for a project I should finish up somewhere around the beginning of December. They are super cute and easy to make. Useful for gift cards, but you will see what I am using them for in the next few weeks.
What You Need
Scissors
Glue
Card Stock
1. Cut your card stock so that it is as tall as you would like +1 inch
2. Then it should be cut so that it is twice as wide as you want your envelop to be + 1/2 inch
3. Fold up bottom 1/2 an inch
4. Fold the sides so that they overlap by 1/2 an inch in the middle
5. Fold the top down 1/2 inch
6. Cut out small side rectangles as shown on both sides
7. Round your corners
8. Fold 1 side down and put on glue then fold other side down
9. Then fold bottom over those and glue down
10. Use for various projects!
