DIY – Square Envelope With Interlocking Heart Closure

After designing my square Valentine’s Day card, I decided to make a square envelope to go with it. I wanted an easy envelope, but one with a little extra pizzaz. So here’s my square envelope with interlocking heart closure.

My valentine cards are 4 inches square. By trial and error, I found that a 6 inch square made the perfect size for my card to fit in.

First I located the center of my paper, then folded each of the corners up to the center.

I started with a 6″ square piece of paper. On the inside of the paper I drew pencil lines (from corner to corner) to find the center of the paper. I folded each of the corners of the square to the center of the paper (see photo above).

Next, I glued hearts to the outside corners of the square paper.

To make the interlocking hearts, I cut hearts out of gold card stock and slightly smaller hearts out of paste paper. Most any colored or decorated papers will work. I glued the gold hearts to the corners of the envelope. I glued so that the corner of the envelope just peeked out of the “v” of the heart.

Next, I glued the paste paper hearts on top of the gold hearts.

Next I glued the slightly smaller paste paper hearts on the gold hearts. This was the first time I used Zig 2-Way Glue. It was like using liquid glue in a ball point pen. I liked the ability to be very accurate with the glue. For those of us who are usually messy with glue, this looks to be a great alternative.

My Valentine card now can slip into the envelope. The hearts interlock, sort of like the flaps of a cardboard box.

These envelopes cannot be sent through the mail. The ones that I need to mail will have to be put into a larger envelope. That’s okay as I think these envelopes are too lovely to be spoiled by postal cancellations.

The envelopes can be made in different sizes, as long as they are squares. A 7.5″ square creates an envelope that’s perfect for a 5″ square card. Experiment with different sizes of envelopes and hearts. Have fun!

Scrapbook papers would make for great envelopes, hearts for the envelopes and cards too.

Play with this envelope and see just how creative you can get.

  1. Candy,
    I made a few “heart-boxes” and took pictures of them. Wanted to send them but that didn’t work. Do you mind giving me your e-mail address ?
