Draw and cut out a circle on your poster board. Make this the size you want your flower to be.
Cover a small piece of poster board with strips of tape on both sides so the poster board is sandwiched in between the tape.
Cut out each strip of tape from step 2.
Cut out small squares from your strip that are about 2 in. wide and 2 in. long.
Form each square into a cone and secure it with a small piece of tape.
Using small pieces of tape, attach each cone to your poster board from step 1. Cover the outside border of your poster board first.
Repeat steps 2-6 to create more cones and, working your way from the outside to the inside, attach your cones to your poster board to create your flower.
Attach a piece of wire on the back of your poster board to hang your flower wreath.
