Round 2: Go through an 8/0 on the next base round (FIGURE 3, a–b). Pick up five 11/0s, then go through the 8/0 on the base round (b–c). Repeat around to point b. Make the second layer with six 11/0s between 8/0s. Make the third layer with seven 11/0s between 8/0s (FIGURE 3).
Round 3: Go through an 8/0 on the next base round. Pick up eight 11/0s for the first layer, nine 11/0s for the second, and ten 11/0s for the third (PHOTO C).
Round 4: Work as in the previous rounds, but pick up 11 11/0s, 12 11/0s, then 13 11/0s for each layer.
Round 5: Repeat, but pick up 14 11/0s, 15 11/0s, then 16 11/0s.
Round 6: Repeat, but pick up 17 11/0s, 18 11/0s, then 19 11/0s.
