How to Assemble Envelope Liners

Did you order my DIY envelope liners, or just want some insight on how to assemble liners best? Then you’ve come to the right place!

Assembling liners is fairly simple. As with most things, there is more than one way to do it, and honestly, you really can’t go wrong with any method. However, below is my personal preferred way to assemble liners!

Materials

First things first, make sure you have everything you need –

• Envelopes

• Liners

• Double Sided Tape

  • If you ordered my DIY liners, you will get this with your order and don’t need to buy anything!

  • If you are a stationer and plan to assemble many liners over the years, I recommend investing in one of these.

Step 1: Open all your envelope flaps

Go through all your envelopes and open their flaps, so that they are ready for the liners to be inserted!

Step 2: Test out your tape

Before using the double-sided tape on your good liners, perform a few test pulls on scrap paper to ensure it is dispensing correctly and to familiarize yourself with its mechanism.

Step 3: Grap a liner

Grab one envelope liner and lay it right side down. (it’s best to start out one envelope/liner at a time, then you can do more as you get more experienced)

Step 4: Tape the Edges

Run your double-sided tape along the liner as shown in the photograph below. You want to cover the top, triangular part of the liner, then add a line down the middle for extra adhesion

Step 5: Insert Liner

Now take the envelope liner, and insert it into the envelope. You’ll want to try to prevent the liner from touching the envelope until you have it in place. 

1. Insert the liner until you hit the very bottom of the envelope

2. From there, center it left to right as best as you can

3. Once in place, press down, adhering the liner to the envelope

Step 6: Fold the Envelope

Grab the right or left corner of the envelope at the center fold, between the front and back flap. Pinch that crease, and slide your finger down the entire envelope, folding the envelope at the crease with the liner inside.

That’s it!

If you want to see how I do this in action, you can check out this video. Also, below are a few extra tips for you!

• Batch work! Once you get familiar with the process, feel free to do more than one envelope at a time

• Not loving this method? Here is another strategy if you want to try something different.

• Oily hands? Rub them with some baby powder to prevent any smudges from getting on your envelopes or liners.

• A lot of stationers also use double-sided tape to close the envelopes. If you have leftover tape, consider this as an option! I prefer using envelope moistener myself, but really, anything with a little extra adhesive works.
