The bad thing about playing so many card games is that the box that the cards come in starts falling apart. I used to tape the box or simply put a rubber band around the cards, until I decided to put them in small storage boxes:
I simply cut the labels from the card boxes and taped them to the front of the plastic boxes. Each box holds the directions to the game and some paper and a pencil for keeping score:
The games our easy to find in our sea of other games, they are protected and everything we need to play is in the container. I got my containers at Ikea, but any small storage container will do!
I just love being organized. It's the little things ;-)
