This is a new line of cards in my collection, I am calling them Mini Messages since they are approximately 3 1/2 x 5", with the envelopes being a little larger. I am selling them in packs of four with two of each of two designs per pack. They are a great size for thank-you notes or to send a short message to a friend. This size will go through the mail, not like my Teeny Tiny Note Collection which are much smaller and do not go through the mail. You can even put a monetary gift inside of these too!
