Its World Card Making Day! Woohoo! When's the last time you took the time to do a little crafty project or write someone a card? Today we celebrate the effort and love behind giving cards to one another. Here at Mixbook, cards mean everything to us. The excitement of a pen pal's card waiting in our mailbox, the suspense to see what beautiful card lies inside that envelope, and the fact that it stays displayed proudly on our refrigerator to relive during our morning coffee.
