Make your own greeting cards

I have always been obsessed with greeting cards and have always had way more than I can send. These days, when I send many more emails than snail mail, I try to buy less. But the lure is still there. I like to have cards on hand for when I go to a party, hate the idea of always having to run out at the last minute to buy a card. I have many blank white cards, too, so I can create my own at the last minute. I created a few of these for friend's birthday parties and made a few extras just to have on hand for when I need a birthday card.
