How to make a DIY Envelope

This is not an exact science but I’ve made several envelopes by using this measurement guideline:

If you card is a rectangle: Make an envelope by cutting a square piece of paper that measures 3″ larger than your cards longest side.

If your card is square: Make an envelope by cutting a square piece of paper that measures 4″ larger.

For example, if your greeting card is 5″ x 7″, you would use a 10″ x 10″ square piece of paper for your envelope. If your card is 7″ x 7″ then you need a square sheet of paper that measures 11″ x 11″.

Use a 10″ x 10″ sheet of paper to make an envelope for a 5″ x 7″ Card.

The birthday card shown below is one of our Free Printable Birthday Cards. The folded card size is 5″ x 5″ so I started with a 9″ x 9″ square piece of paper. I used craft brown paper but you could use any paper you have on hand – patterned or colored paper.

Start with an 8" x 8" sheet of paper. Position the paper like a diamond and place the folded card in the center. Fold all four corners in using the sides of the card as a guide. Unfold the paper and snip triangle corners where folds overlap. Fold the two side flaps in. Add glue to the bottom flap to complete your envelope.
The card shown above is 5″ x 5″ and the [paper size for the DIY envelope shown is 9″ x 9″.
