Fold 2 rectangular pieces of construction paper in half. 1 piece will be the outside of the card & 1 piece will be the inside. On the inside piece, cut 2 short lines near the middle of the fold. Fold the 2 outside flaps that you just made (but do not fold the middle flap). Unfold the flaps. Open the card.
Push the 2 flaps towards the inside of the card – they will form 2 step-like protuberances. Open the card.
Refold the card. Cut 2 short lines through the folded flaps on the sides. Fold the outside flaps that you just made. Unfold the flaps.
Cut some small hearts, stems & leaves from construction paper. Decorate them with crayons or markers if you like. Glue the stems, leaves, & hearts to the flaps. Make sure that the hearts do not stick out of the card when the card is closed. Glue the card to the other piece of folded construction paper. To make sure that you do not glue the flaps down, apply the glue only to the inside of the card and then carefully place it on the outer card.
