Envelope liners are pieces of paper or card stock that are adhered to the inside of an envelope.
Originally, envelope liners were used to protect the contents from the elements or even from the envelope itself (such as a colored envelope rubbing off on a letter).
They're not terribly common with every day mail, but they're gaining popularity for wedding invitations and formal events. These are a cost effective upgrade to really add additional design elements to your suite. They can be patterned, a photo, or even just one solid color.
We can color match your liner to your envelope, or find something complimentary!
