In this project, we were practice the skill of making a ball. first we bought a grape fruit, then we used plastic bag to cover it and using tape to cover the whole ball. Then, we use marker to draw some lines on the ball and cut the tape through the line on it. Next, we got two parts and we added notches to make the tape of the pattern flat. Finally, we traced the pattern to the fabric and made the ball cover. We also designed a different ball pattern. In addition, we practiced the sewing skill on a sewing square.
