I make smaller cards on the computer - they're credit card-sized, and I laminate them. Because they're so small, they fit very easily into the small wallet I use when traveling. I measured a credit card and made sure that the dimensions of my cards were just slightly smaller than a credit card.
Do you happen to have it saved that you could email it to whagerty@mdirect.net? Just so I have an idea of what you put on them. I really like the idea of credit-card size so I can stick them in my fanny pack

I got one of those lime green mickeys from h/depot and typed everything out (reservations were my goal) then shrunk it and glued it on, laminated it with those small sheets and put a hole punch thru it, used a colored rubber band thru the hole and WAH LA, hung it outside on my backpack, SO HANDY and cute too!
I'm clueless about these, are they shrinky dink things you can buy at home depot? Sounds cool.
