I have the perfect idea for you. Your ornament will look like a quilted ball! I wish I had a pic, but hopefully I can explain clearly enough for you to try it. Just take small prices of fabric...all different shapes are fun...about a square inch in total size. Take one piece, lay it somewhere on the ball of styrofoam. Using something on the sharp and narrow side...I have used metal toothpicks, yarn needles, a nut pick etc...begin gently pushing the edge of the fabric into the strofoam, all the way around the perimeter of the fabric piece until all the raw edges are "buried". Take another scrap of fabric, Lay it right next to the edge of the first piece and do the same. Continue this until the entire ball is covered. It will look like a puffy quilt ball. Take some ribbon, create a loop, put a pin through the loose ends of the ribbon and insert the pin into the ball for the hanger. They are SO quick and easy. Have fun!

there is a u tube video for quilted ornaments sorry I don't know how to tag it for you but the are easy

I saw some cute styrofoam balls covered in homespun at a little craft store and just laid in a wooden bowl. You could cover yours with Christmas fabric and put them into a pretty Christmas bowl instead. I am going to make some for Christmas later.
