The pattern does not give yardage amounts, only the number of skeins needed.

I believe the skein totals listed in the book reference the old skein put-ups of 143 yards and not the new size of 115 yards and the yardage amounts were calculated using the higher yardage skeins.

Sizes given are:
Chest: 36, 39.5, 43, 46.5 (inches)
Length: 20.75, 22.75, 24.75, 24.75 (inches)
