Summarize the following:
This is basically oval-ish, round or like a teardrop, your choice. Leave a small straight piece at the base; wind one of the wires around the other to secure the circle shape. You'll need each piece to be large enough to cover the circular shape you've just formed but not so large that it sags. Once you have a good size cut, use that as a template for the rest of the pieces. Wrap green florist's tape around to hold the stocking piece firmly in place. You will need five petals to form one flower. (And obviously, make as many petals as you want flowers in total).

Summary:
Bend a piece of wire into a petal shape. Pinch the base together. Cut out the nylon stocking. Stretch the stocking piece over the wire tightly. Repeat four more times.
