The Equilateral Hat pattern is formed by knitting triangles in a continuous strip which is folded into shape when sewing the hat up. It is sized for an average head but Lucy explains how to make it smaller or larger by altering the size of the triangles.
You can use almost any yarn - Noro is recommended - this pattern is ideal for using up oddments.
There are four pages of instructions together with a full color photo of the hat. The pattern is housed in a polythene sleeve ready for filing.
