Materials Needed:

Poke a hole with a pencil in your styrofoam ball. Cut a 3 to 4 inch piece of ribbon. Join the ends of the ribbon together and stick into the hole and file the hole with glue.
Place a rose, bud up, into the hole and press firmly. Cover the ball with hot glue (use low setting) about a quarter in size at a time. Do not cover the entire ball with glue at one time as it will glue much faster than you can cover it.
Press the roses into the hot blue as you go along, covering the entire exposed surface of the styrofoam ball. Continue until the entire ball is covered.
