One-color hat with flower takes one skein; two-color hat takes two (hence the difference in yardage).
Pattern gives directions for two sizes: small (18” circumference) and medium (19.5”)
from the book: “This easy hat is knit in the round with alternate bands of knit and purl stitches for texture. If you’re a beginner, don’t be daunted by the double-pointed needles used for the decreases at the crown. They’re simple to use and you’ll be pleased with the seamless results. The flower is fun to make and transforms the hat from a beanie to a stylish cloche.”
