dec·a·gon·less (dĕk′ə-gŏn′less)
n.
Without having a polygon with ten sides and ten angles.

For those that don’t want to knit the Decagon Hat with the decagon top.

Like the Decagon hat, this uses a total of most of a ball of yarn (~80g), and you can use up some of the scraps that breed in the dark corners of our stashes. Each set of stripes takes ~7gm of DK/worsted weight yarn.

Gauge is relative and please use whatever needles will get you ~20 inches for 120 stitches in the round.
