This hat is made from the bottom up, holding one yarn at a time, with slipped stitches making the colorwork patterns (no stranded colorwork!).

A photo tutorial is included for the twisted stitches which create the unique zig-zag pattern.

The pattern is both written and charted.

You need

• for shorter heights, approx 105{145, 185} yards / 95{135, 170} meters total for small{medium, large} circumferences
• or for taller heights, approx 135{185, 235} yards / 125{170, 215} meters total

-- DK weight yarn (or light worsted) in two colors, approx equal amounts main and contrasting colors

-- fitted sample is in Local Color Fiber Studio Rambouillet DK, one partial skein each color, main color is Madder Root dyed (red, 63 yards / 58 meters used), contrasting color is Indigo dyed (blue, 73 yards / 67 meters used) for medium circumference, shorter height

-- slouchy sample is in same yarns, 110 yards / 101 meters used of main color (red), 113 yards / 103 meters used of contrasting color (blue), for large circumference, taller height

• size US 7 (4.5mm) needles for working in the round (either a long circular for magic loop throughout, or double pointed needles throughout, or a 16˝/40cm circular and double points for the crown)

Sizing
Circumference is small{medium, large}, approx 16{18.5, 21} inches / 41{47, 53} cm, unstretched, measured at bottom (ribbing) after blocking.
It should be worn with 2-4 inches / 5-10 cm of negative ease, on head sizes of 18-20{20.5-22.5, 23-25} inches / 46-51{52-57, 58-64} cm.

Choose a height based on your circumference size; for reference, for a standard adult hat, around 8 inches / 20 cm is a standard hat height (not slouchy).
Shorter: approx 7{8, 9} inches / 18{20, 23} cm.
Taller: approx 8.5{9.5, 10.5} inches / 22{24, 27} cm.

Hólm is a hat in two colors and two textures (not including the ribbing), starting with a zig-zag pattern covering all or most of the circumference above the brim. The dot pattern grows outwards as the hat grows taller, eventually taking over, so the crown is finished with only dots.

The background color of the dots pattern is labeled as the main color yarn since it’s used in more rounds, but that means the contrasting color is the primary hue in the brim and on the zig-zag pattern, so the colors are basically equal, dividing the hat in half.

You’ll get a bit of a different look whether you make a taller or shorter version—on the taller hat, the zig-zag pattern is joined just about all the way around at the bottom, whereas on the shorter hat, you’ll start out with a chunk of dots pattern at the bottom.
