Of cards, books, and calendars, cards are the easiest to create, since they have room for only a single photo and minimal text. Here's the basic process:
To create a card:
Select the photo that you want to appear on your card.
Click the Card button under the display pane (Figure 7.1).
Figure 7.1. Click the Card button with a photo selected to make a card from that photo.
In the card design dialog, choose Greeting Card or Postcard from the pop-up menu and select one of the theme previews (Figure 7.2).
Figure 7.2. Next, choose your desired card type from the pop-up menu and pick a theme from the scrolling list of themes.
iPhoto creates your card (Figure 7.3).
Figure 7.3. iPhoto creates the card in the Source pane to the left, showing the front and inside of the card in the display pane.
For the front of the card, choose the desired background and design from the Background and Design pop-up menus (see the facing page), and add and format text as desired to the back or inside of the card (flip forward a few pages for instructions on different ways to format text).
When you're done, click the Buy Card button, and run through the process of ordering your card.
If you're not sure which of several photos you might want to use, you can select multiple photos before creating the card, and then drag different photos into the photo slot on the front of the card to see how they look.
Greeting cards are 5" x 7" with a picture on the outside and text on the inside; postcards are 4" x 6" with a picture on the front and room for text or text and an address on the back.
