Receiving ATCs is just as much fun as making and sending them out! Not only do you have cards to add to your collection, but you can learn so much from the different ways other artists have used to create them. I don't think I've received any made the same way twice.
The most recent set I've received came from Origami Grace. It was for a blind swap of 3/3. I loved them all. One of the cards was especially delightful. Grace created an origami heart, tied on a gold thread, then affixed this to the card as the centre point.
