hand written envelopes
If you really want to make your main invitations really unique you may opt for hand-writing your names and addresses. According to the color of your invitations, and most of all the color of the envelopes you have chosen, I will suggest the best option. For example, you may match the color of the ink with the one of the wax seal, or, on the other hand, you may highlight a contrast between the color of the envelopes and the addresses.
For all the info about the main invitations, the types of paper, printing techniques, colors of the envelopes and working processes, fill in the form to receive the smart new 2018 CATALOG.
