Add a pop of color to your invitation with your envelope and mats (pictured in black). If you order a pocket fold card, you'll get a belly band in this color too.
 
You have the option to add addressing to your envelopes in a font that matches your invites. Return addresses are printed on the black flap of your invitation envelope and onthe front of your RSVP envelopes. Dark envelopes cost a little more to print with white ink.
