Cut a 14.5x29cm piece of white cardstock and score and fold in half. Draw a 2.5x8cm rectangle on the fold line inside the card blank.

Use a craft knife to cut along the two 8cm lines which go across the centre line and score at the top and bottom. Fold this piece inwards so that when the card blank is open it pops up. Adhere the pop-up mechanism to the inside of the card blank making sure the pop-up piece is not stuck down.
