Protect your cards from the keys in your pocket – put them inside a milk carton case!
1. Supplies: A milk carton, scissors, clothespins, multi purpose glue and a paper cutter. 2. Open the milk carton´s seam from top to bottom. 3. Cut out two sides and the little flap which was on the inside of the carton. Straihten the sides with a paper cutter. 4. Glue it together and use clothespins to keep pressure.
To avoid cards from falling out of the case, always keep three cards inside. To open the case simply squeeze gently from both sides.
