From your two pieces of coloured card or construction paper take one piece and fold this in half.
With the second piece take your scissors and cut a small amount off one long side and one short side. This is so when you stick the two pieces of card together the inside part doesn't stick out. Fold the smaller piece of card in half as well and then check that they fit ok but placing the smaller piece of card inside the larger one and closing them. If you can't see the inside card then you cut off enough!
Take your inside piece of card and cut four slits into it from the folded side towards the outside. These will be the parts that you stick your Batman and Robin printables on so it's best to do these in two groups of two cuts. Opening your card back out push the two cut sections outwards and pinch the edges so that they will stay put when you open and close the card.
Write your message in your card. We went with the one from DC Comics "To Dad, Thanks for being the (Batman) to my (Robin). Happy Fathers Day"
Put glue on the back of the inside par of your card - except on the pop up bits you just cut out - and then carefully stick it into the second piece of card, ensuring that the folds on both cards line up and the the pop up part of the card is popping outwards.
From your printable cut out the Batman and Robin images. Place a small amount of double sided sellotape on the back of these and then stick them into place on your card. Your DC Comics Fathers Day card is finished and ready to hand to a very lucky person!
