we started out by covering a softball in plastic and tape until it was completely covered. Once it was, I drew lines where the stitching was, and then cut along those lines to remove the plastic and tape from the ball. The first pattern that emerged from this assignment was the 2 piece pattern that came from the softball stitching, and the other one was a three piece pattern that I came up with.
I then cut into parts of the pieces to make them lay flat. Once they did, I traced them onto paper, including all notches
