With a straight pin, secure one end of A to ball. Continue to wrap A around ball, working in the same direction and placing each new wrap about 1/4 in. (.5 cm) further from the last wrap.
Finish at the opposite end of the ball from where you began. Cut yarn and secure end to ball with a second straight pin.
Note:Beginning and ending at opposite ends of balls ensures that you have an uneven number of wraps for weaving.
Cut a 3 yd. (3 m) length of A and fold it in half. Thread the folded end into the blunt needle and begin weaving over and under the wrapped strands, leaving a yarn tail about 1/2 in. (1 cm) long. Take care to go over and under each wrap in order, you can thread them closer to the middle of the ball if it makes them easier to differentiate, but take care to draw the woven strands tightly to the top of the ball and to each other as you work towards the center of the ball. The tighter you can weave the less chance there will be for the wraps to slip when the embroidery is added!
As you complete the first and succeeding rounds, take care to work over the yarn ends, hiding them under the weaving. When you run out of yarn, repeat the process, overlapping the ends by about 1 in. (2.5 cm) and hiding the yarn ends as before.
When you've covered the top half of the ball, turn it over and begin weaving from the opposite end, until ball is fully covered. Remove pins when weaving has been completed.
With desired color of B, work embroidery using straight or chain stitches as desired to create simple designs on the surface of the woven ball. Placing pins or rubber bands around the ball can help to guide your stitches and keep them evenly spaced. Hide yarn ends by burying them behind the woven strands.
