Use some precision cutting scissors to cut the egg carton into various shapes, as shown in the photos.
Paint the flower petals or succulent petals using your watercolor or acrylic paints.
After the paint dries, glue the layers together using your hot glue gun.
Place the flowers in a teacup, small pots, or even an unused egg carton for a pretty display. You can also attach them to a canvas for wall art.
(optional) If you use mini terracotta pots, add a bit of newspaper and gift bag filler to prop up the flowers.
