Making Envelope Liners – Not as Hard as You Think

My mother-in-law is celebrating a milestone birthday soon, and to celebrate, my husband and his brother are throwing her a party at a rose garden so she can play bridge with her friends. She has great sons, huh? (and great daughters-in-law, too).

I took on the project of designing and printing the invitations, and I just had to make custom liners. I always say that the invitations set the stage for the party, and liners bring any invitation up a notch and can help showcase the theme. So we made custom liners for 100 envelopes! Somehow I convinced my husband to help, too.

Because really, it’s not that hard.

How to Make Envelope Liners


  • Envelopes
  • Cardstock – one sheet for template
  • Paper (scrapbook paper, wrapping paper, etc.)
  • Scissors
  • Pencil
  • Gluestick

Envelope Liners Materials

1) Choose your envelopes and decide on the liner paper.

It doesn’t matter what kind of envelope you’ll use—pointed flap, flat flap, big or small—because you’ll make a custom liner template that fits exactly.

For the liner paper, you can use any lightweight paper or cardstock. Scrapbook paper and wrapping paper work great for this.

I wanted liners that worked with the bridge-party-in-a-rose-garden theme, so I chose designs that were black, white or red, and I wanted flowers to allude to the garden. For the tutorial, I chose red paper with white polka dots.

2) Next create the liner template

Use a piece of cardstock for your template. Place the bottom of the envelope on the bottom edge of the cardstock and trace around the envelope with a pencil. (I’ve outlined the pencil line with a marker, so you can see it.)

This isn’t the end however. If you used this outline, you wouldn’t be able to fit the liner inside the envelope or seal it shut. We need to make the template smaller.

Make the template smaller
1.    Move the envelope 1/2 inch down and trace the outline
2.    Then move it to the right 1/2 inch and trace the left edge
3.    Move the envelope left 1/2 inch and trace the right edge

Cut along the inner-most lines. Don’t worry, you can do it. Just like they said in driver’s ed… go slow around the curves.

3) Trace the template onto the paper you’ll be using for the liners

(In my example, the template is the liner).

4) Place the liner inside the envelope

Move it so the top of the liner so it sits just inside the glue line at the top edge of the envelope. It doesn’t matter where the bottom edge of the liner is—no one will see it.

5) Fold the envelope flap

Holding the liner tight where you want it to sit, fold the flap of the envelope and the liner closed.

6) Glue the top of the liner to the flap

Open the envelope flap back up again and use the glue stick to glue around the edges of the part of the liner that will attach to the flap. Don’t worry about gluing the rest of the liner. Only the flap matters.

7) Insert your invitation and mail!

Wait for the calls about how beautiful the invites are!
