How to... 3D house cards
Cut a 14x28cm piece of white card, and score vertically down the centre. Rotate the card to landscape and then score it from top to bottom at 7cm, 14cm and 21cm.
Look for the scored square shape in the middle of the card. Score diagonally across it in both directions. Cut a 2cmwide strip from each corner of the area outside of the square.
Fold the diagonal folds as mountain folds and tuck in the sides to form the roof shape. Fold the walls in to form a cross shape that will stand up. Glue the roof folds to secure.
