If you can trace a circle, you can make it.

Trace outer edge of ring onto a piece of poster board; cut out.
Glue poster board to ring form.
Position 7-inch cones to slightly exceed edge; hot-glue in place.
To create second ring, stagger 7-inch cones and hot-glue them to first ring, tacking to each other as you go. Repeat with 4-inch cones, working toward center. The cones will gradually become more upright.
Tack points of innermost cones to poster board as well as to each other. Let dry completely, about 5 minutes.
