I decided to alter the original project to make it more mailable. Here are some of the items I created.
I used the Crazy About You stamp set for the stamped sentiments on each card.
These are all small cards, about the size of a regular 'gift enclosure' card.
I also used the Sale-A-Bration papers, Irresistibly Yours, on each of the cards and sponged them with color. I really love these papers and hope that Stampin' Up! will have more of this type of paper available in future catalogs.
