How to Line Your Own Envelopes

Lining Your Own Envelopes is Easy

Lining your own envelopes like a pro is easier than you might think! Simply slide our pre-cut liners inside of your envelopes and adhere with your favorite glue or double-sided tape. Envelope liners do not contain any adhesive.


IMPORTANT: Don’t overdue the glue!
This may cause wrinkling, color bleed, and an overall poor appearance. Just a bit of glue or tape around the top perimeter of the flap will work just fine. We recommend lining one blank envelope and allowing it to sit for 24 hours to determine if you are happy with the results. If you are, then you can line all of your envelopes.


IMPORTANT: Print your envelopes before lining them!
We recommend printing your envelopes prior to lining them. This will make it easier for the envelopes to run through a printer and will ensure that your liners don’t detach during the printing process.
