Pop up cards are a fun alternative to everyday, simple folded cards and are more simple to make than you might think. A floral themed pop up card works well with the pop up design, as it will make it look as though the flower is growing or popping up out of the ground. You can write a message on the front of the card such as, "My love for you..." and then continue on the inside, "Grows and grows."
Fold a piece of construction paper in half so the shorter sides touch. You will be constructing a card that opens from the bottom with the fold at the top of the card, rather than opening like a book. Cut two small parallel slits into the fold at the top of the card, about an inch long.
Open the card and poke the cut piece from the back of the card into the centre of the card. Reverse the direction of the fold so you have a small loop of paper that juts out inside the card.
Close the card and crease the folds along the top. There will be a rectangular shape missing from the top of the card where it folds to the inside.
Draw a simple flower shape on another piece of construction paper in markers, making a circle for the centre, adding oval petals around the circle, and drawing a thick stem with leaves branching off to the sides.
Cut out the shape and glue it with a glue stick to the inside of the card onto the front face of the jutting out, step-like loop of paper. Be sure the bottom of the flower is in place above the bottom of the step so the card can fold back down.
Write a message on the front and inside of the card along with your name and the recipient's name.
