Cut out a simple house shape from the cardboard, about 4 inches wide and 6 inches tall. Then paint it brown to resemble gingerbread, and let it dry for at least 15 minutes.
Use a craft knife or scissors to cut a small door in the center, about 1.5 inches tall. Leave one side attached so it can open like a flap.
Glue your child’s photo behind the door opening, making sure the face is visible when the door is lifted.
Decorate the roofline with pom-poms or beads, arranging them like candy drops. Add foam or felt pieces to form windows, shutters, or gumdrop trims.
Add finishing touches like glitter, sequins, or even faux frosting lines using white paint. Let everything dry completely before hanging it on the tree.
