I love envelope liners because they add elegance and flair to any envelope! They also look deceptively complicated to DIY, so I thought today I would offer a short and sweet tutorial over how to make your own. All you need is an envelope, a pretty piece of paper, glue, scissors, and a pencil to get started! The first step is to address your envelope, preferably in pretty calligraphy like the Janet Style envelope pictured below. The reason it’s best to address the envelope pre-liner is the liner may make the surface of the envelope less smooth than it could be, which could lead to bumpy writing or unexpected spatters.
Next, choose a piece of paper for the liner. Anything will work, really, except for heavy card stock! I have chosen to use the blue tuile pattern from the Parisian Printable Bundle, which is my current favorite envelope liner because of the pretty drawings. Once you’ve chosen your paper, trace around the envelope in pencil, making sure the flap is open.
You don’t have to trace all the way to the bottom of the envelope; as a general rule, it’s good to trace around at least 2/3 of the envelope.
Next, cut around your pencil guidelines.
At this step, the liner is almost ready to go in the envelope. However, the liner is currently the same width as the envelope, which means it’s too big to fit inside! To fix that problem, trim a little bit (~1/8″, 3 mm) off of both sides of the envelope, taking care not to cut where the top of the liner starts to taper.
You can see in the photo below that I only trimmed off the straight sides, not the slightly taped top.
Once you’ve trimmed the sides, use an eraser to get rid of any trace of the pencil guideline you used to cut the liner.
Slip the liner into the envelope; the liner probably won’t extend all the way to the bottom of the envelope, and that is perfectly okay! Just play with the liner’s positioning until it’s right where you need it to be (i.e. not obstructing the envelope adhesive).
Fold the envelope flap down, taking care to apply pressure to the top of the envelope. The goal here is to create a crease in the envelope liner.
When you open your envelope, the envelope liner should have a visible crease in it.
Take the envelope liner out of the envelope, and put it face-down on a piece of scrap paper. Use a glue stick to apply adhesive to the sides of the liner.
You can also use double-sided tape or brush regular white glue on. Do not put on dots or squiggles of white glue, otherwise the envelope liner will be wrinkly when it dries.
Once you have applied your glue, restore the liner to the envelope. Line up the crease in the envelope liner with the envelope flap’s crease, and apply pressure to the glued parts to get the liner to adhere to the envelope. That’s it!
Though creating DIY envelope liners is a simple process, it can admittedly look a little complicated when broken down into so many steps. To help you learn how to make envelope liners, I have created this short tutorial video! It implements all of the steps above, except on a pointed-flap envelope.
I hope you enjoyed today’s tutorial, and that you got some ideas for future card-sending and letter-writing endeavors (especially since the holiday season is fast approaching)! Here’s a suggestion if you are sending out a lot of one type of envelope (e.g. for wedding invitations): you can make a template using the process outlined above, and trace around it to create several envelope liners. I can’t think of a better way to add style and a little bit of extra protection to snail mail!
If you have any questions about creating DIY envelope liners, of course feel free to ask! Otherwise, thanks so much for reading, and enjoy the rest of your day!
