I recently made ten boxes of cards for our Altrusa Club convention. I came up with four different sets of cards. We gave them away as door prizes. This is the third set.
I made two boxes of this set of cards - each had 6 cards, one each of 6 different designs
The card boxes were colored with the water color crayons.
Then I pulled one card design to each box front, so the card boxes looked different from the outside, but they really had the same cards inside!
