Out of all the projects that I set out to do this was by far the easiest. "Easy" meaning it caused the least amount of time and aggravation.
Cut out 1/2 inch fabric strips, making sure that they will wrap completely around your styrofoam ball. I used 5 inch styro balls.
Wrap the fabric and pin. I didn't want my pins to be too visible so I bought some that were very small.
Repeat with each strip of fabric until the styrofoam is no longer visible. The end. I was so happy with these that I almost considered not finishing my thumbtack vase fillers. If only I hadn't already put over a thousand tacks in the four small styro balls. That project will come later.
