Most people get stuck with the explanation after round 43. You crochet round 43 in spirals, from round 44 you work in rows. The trick here is to literally do what it says, and think about what it should look like: this will be the white point on the front of the bus. Don’t worry about the fact that it looks a bit skewed because you work back over row 44 and 43, you won’t see that anymore.

44. 7 sc, leave the rest of the st unworked.
45. Ch 1, turn around, work back over the 7 dc and dc from round 43, but work in the back loops only (leave loops inside the box clear), 16 sc
46. Ch 1, turn around, sc 2 st together, 12 sc, sc 2 st together (= 14 sc)
47. Ch 1, turn around, 2x (sc 2 st together), 6 sc, 2x (sc 2 st together) (= 10 sc)
48. Ch 1, turn around, 2x (sc 2 st together), 2 sc, 2x (sc 2 st together) (= 6 sc)
49. Ch 1, turn around, sc 2 st together, 2 sc, sc 2 st together (= 4 sc)
50. Ch 1, turn around, 2x (sc 2 st together) (= 2 sc)
51. Ch 1, turn work, 2 sc
52. Ch 1, turn work, sc 2 st together (= 1 sc) Fasten off.
