Although they are not the cheapest, I love the cards from moo.com. I use them for both full-size business cards for my business, as well as half-size "mini cards" with my photo
(both biz ones and personal calling cards). The "mini cards" fit in a nifty holder on my keychain. The card stock is very nice and thick. The best feature is that you can have a different image (design, photo
, text) on the back of every card in a pack of 100. So, can't choose from among all the amazing photos of your beloved boat? Go ahead and use several!
