Beautiful Egg Carton Wreath. If you have kids they will have a lot helping you make this wreath. Cut up old egg cartons. The portion that holds the eggs was turned into various flower shapes. Some with rounded petals, others fringed. We cut out some of the pointed in-between pieces for flower centers. We used the flat top and sides of the egg carton to make leaves. Then paint and let dry. Cut out a large cardboard circle from an old box. paint dark green dry. Assemble with glue gun.
