Read the following context and answer the question.
Context: I decided that I wanted the back of the postcard to be simple , lots of blue , and I wanted my contact information and website listed there . I really liked the idea of putting beautiful stamps on this card design , and I picked the stamps out ahead of time at the post office . Lots of blue , repeating spirals , and showing off those gorgeous deckle edges . The last touch was grommets added to make the postcard design easy to display , and then packing for shipping . The postcard went out on Thursday and I got a call from the gallery this afternoon that the piece had arrived safe and sound .
