Pattern Note

Hat is knit from the bottom up with the “scoop” being worked in the round and the “cone” worked back and forth in rows. While the cone could be knit in the round, the fabric’s inherent spiraling made the round join too visible on the front of the hat, while working in rows keeps the center back seam in the center back.



With smaller needles and A, CO 88 sts, join for working in the round, being careful not to twist. Use stitch marker to denote start of rnd.
