From a free pattern by Arlene Williams (firstname.lastname@example.org).
Yarn: 1 skein Noro Silk Garden in colorway 243B, 1.5 skeins Noro Retro in 3B (blue). Total yardage: 275 yds.
Needles: US size 2 circular and US size 4 circular
Mods: The Noro Retro is thicker than the Silk Garden, so I adjusted my row count accordingly on the second (mostly blue) half, going by the total length of fabric, rather than the number of rows. Also, I knit all of the hat except the crowns in k1p1 rib, for a snugger fit.
