DIY Envelope Liners

Creating your own envelope liners is an easy way to really elevate your card making. Not only does it make the envelope feel nice and sturdy, but it also gives a "wow" factor when you open the envelope! Today we are going to show you how to create a liner template for any size envelope! 

Below you will find instructions for hand-cutting your own liners. However, if you have an electronic die-cutting machine, you can use the SVGs listed in the supply to create your stencils, and skip the measuring. 

Supplies:

STRAIGHT FLAP

To get started, we are going to choose some patterned papers to go with the envelopes we are lining. We chose some Straight Flap envelopes in the colors Parcel Wrap, True White, Paver Red, Brown Box Kraft, and Whip Cream. We will cover Euro Flap envelopes after these. 

 

DIY envelope liners Paper Choices

 

Take a sheet of white cardstock and trace your envelope onto the sheet.

Measure the top of your envelope where the sealing strip is so that you can be sure your liner will sit below the sealing glue.

Using that measurement, draw a line across the top of your liner template.

Then measure 1/4" from the left and right side of your envelope and draw a line on each side.

Next, measure 1/4" on the diagonal sections at the top and draw a line.

Cut out your template with scissors.

Check to make sure your template fits in your envelope. You do not want the liner to go all the way to the bottom of your envelope or there will not be room for it to move up and down when you open and close the envelope. Trim 1/4 inch off the bottom if the liner touches the bottom of the envelope. 

 

Checking template fit

 

Now trace your liner template onto the back of a piece of patterned paper. Do not worry if your lines aren't perfect. No one will see them once you are done.

Cut your liner out around the lines you traced.

Add a strip of adhesive to the very top of the envelope liner. Gluing it at the top only will allow it to sit securely, but still fold properly when you close the envelope. The part below the fold moves up and down slightly when opening and closing the envelope, so you do not want to glue more than the top. 

 

Adding adhesive to envelope liner

 

Insert the liner with adhesive into the envelope and line it up just below where the glue strip is.

Just that easy! Look how beautiful these Straight Flap envelopes are with their new flair! Now just add a card and send it off in the post to make someone's day!

To make things easier, we created a template for each envelope size we carry so we can have them on hand anytime we want to line an envelope. Simply trace and cut and you're done!

EURO FLAP

Making envelope liners for Euro Flap envelopes is even easier than making Straight Flap liners. You will start out with the same supplies as above. 

Lay an open Euro Flap envelope on a piece of sturdy white cardstock and trace it. I like to use 100lb Sweet Tooth cardstock so I have a template to use for all further liners. Then cut it out with scissors around the traced lines.

Once you have your liner tracing cut out, measure 1/4 inch on the left and right side and draw a line on each side using a ruler. Draw another line one inch from the bottom of the template as well. Cut the two sides and bottom off along those lines. Now your liner template is ready to go!

You can trace this onto the back of a sheet of patterned paper and glue it into any Euro Flap envelope. Only add glue along the top of the liner. Gluing it at the top only will allow it to sit securely, but still fold properly when you close the envelope. The part below the fold moves up and down slightly when opening and closing the envelope, so you do not want to glue more than the top. 

The liner will have a bit of space at the bottom and should not touch the bottom of the envelope.

You can use this same technique to create a liner for each size of envelope you use.
