a hat using double-knit increases and decreases
This hat is a simple application of decorative increasing and decreasing in double-knitting. Six banners or flags in 3 different Celtic knot motifs run diagonally around this hat and up to a spiral at the crown.
Sizing this hat is very easy — the banners stay the same, but you add more pairs between them if you need a larger size. The larger the hat, the more dramatic the crown spiral becomes! The crenellated brim is a function of the increases and decreases, and also becomes more dramatic the more pairs are inserted between the banners.
This pattern is currently available only in Extreme Double-knitting.
