Cut out your egg cartons and make round the edges when cutting so that they look more like petals.
Paint your egg cartons. Now you need 5 egg cartons painted pink and 5 purple. Place the pink egg carton each purple one. Put some glue on the inside of the purple egg carton and then put the pink one on top.
Fold over your pipe cleaner. Then push the top 2 pieces through the egg carton holes. Twist the pipe cleaner all the way down so that the two halves come together and make the pipe cleaner stem stronger.
Glue your button on top of the pipe cleaner in the center of the egg carton. Twist the pipe cleaner a bit before gluing the button down. Paint some Popsicle sticks with blue and yellow and glue the sticks.
Now add some paper filler inside your can and place your egg carton flowers inside.
