“Mosaico” a Fair Isle hat. I created this hat pattern thinking of the mosaic knitting patterns. It is a Fair Isle hat with a folded rib band. This hat is definitely a unisex hat and you may size it smaller or larger. It has the ability to be a Tam, slouch or plain beanie depending on your gauge and blocking choices.
A mosaic (from the latin mosaĭcum opus, ‘work relative to the Muses, artistic’) is a painting made with small pieces of stone, ceramic, glass or other similar materials of different shapes and colors, called tesserae, United through plaster, or other Binder, to form decorative geometric or figurative compositions.

Pattern Notes: If you substitute the yarn, go with Sport yarn with the same Wraps per Inch (WPI)

Needles: US 3, 3.25 mm double pointed needles or 1 or 2 circular needles with cable of 30 ” (or bigger if you are looking to make the hat using magic loop). At one point DPNs will be useful.

Gauge: 2 “ = 12 Sts and 16 Rows in Stockinette Stitch (adjust needle size to get gauge if needed)

Notions: Stitch marker, Darning needle, enough waste yarn for provisional cast on, crochet hook.

Finished dimensions before blocking: Rib band measures about 18 (21, 24, 27) inches, if you get gauge. Blocked this hat measured from crown to purl edge about 9 ½ inches tall and 22 inches in the round. Blocking this hat consisted of the hat being hand washed, then laid flat to dry. I used a towel to remove the excess water, by patting it to an almost dry point. You may use other ways of blocking as for a tam or a bigger slouchy form. It has a negative ease of about 1 to 2 inches.
