Curve-Flap Valentine’s Day Card Supplies needed: A printer A piece of paper (pink or red construction paper works well) A pencil Scissors or pinking shears Glue Optional: Heart stickers Go to the template page and print it (pink or red construction paper works well). For a smaller template, click here. You can use your printout itself as a single card, or use it as a template, tracing it onto gift wrap, a wallpaper scrap, or other fancy paper that is suitable for a Valentine. Carefully cut out the Valentine card (you could use a pinking shears instead of a regular scissors to give your envelope an unusual jagged finish). Write your Valentine message on the inside of the envelope. Fold over the flaps, one at a time, on top of the central square. When you get to the last flap, gently push one edge of the flap under the first flap. Put the name of your Valentine on the other side. You now have an unusual envelope/letter with curved flaps. If you want to seal it, you can either tape the flaps down securely or put a pretty heart sticker where the four flaps meet.
