To begin, cut approximately 15, 3-inch squares of felt. Take one felt piece at a time; fold each square into quarters, as shown. Round off the edge of your folded piece with your shears, making sure to leave the folded corner intact. When you open up your piece it should be like a circle.
Using scissors make a snip on your circle, cutting just to the center of the piece. Apply a small dab of glue to one of the flaps formed by the snip.
Now overlap the other flap so that your piece forms a shallow cone. One of your flower petals is now complete! Repeat the above steps with the remaining felt squares to make the rest of your petals.
Use scissors to cut a cardboard circle that is about 3 inches in diameter. Apply a dab of glue to the outer edge of the circle, and then affix one of petal pieces to the cardboard, so that the snipped portion of the petal is affixed to the cardboard.
Continue affixing the petals to the cardboard base in a similar fashion, overlapping them slightly as you work and then add another layer of petals at the center. Finish your flower with a decorative brooch adhered to the center to cover the blank space.
