Folded or flat?
A folded card feels more personal: the message is inside, out of sight until it is opened, and there is room to write. A flat card is quicker to write and costs less to mail. For flat thank you cards with a back to write on, see our thank you cards; for folded ones, start here.
For customers and clients
Slip one in with an order, hand it over at a closing, or mail it after a big job. Put your logo on the front or back, a short printed thank you inside, and leave room to sign. Writable paper takes any pen, so a handwritten line beside the printed one never smudges.
For weddings, showers and donors
Gratitude in a serif, thank you in script and the heart card suit wedding and shower thank yous, and the donor's note is the same card with your organization on the back. Order a few extra for the gifts that arrive late.
