Cut egg cartons to resemble flower petals. Consider cutting a fringe design, larger petals or slits in between petals. This will help the egg carton cups open up a little more.
Match two different cut egg carton cups together to make your flower base.
Use acrylic paint to paint the egg carton flower petals.
Let the painted egg carton fully dry.
Poke a small hole in the bottom of one egg carton flower cup.
Bend the floral wire in half.
Poke the wire through the hole so that 1/4"-1/2" is sticking out. Bend the ends and hot glue.
Add a small dab of hot glue on the bottom of the egg carton flower to help support the weight of the egg carton.
Hot glue a button in the center of your flower craft.
