Clyd: 1. warm n.m. sheltered n.m. snug n.m. cosy n.m. pronounced kleed. Welsh
Clyd has been donated to p/hop by designer extraordinaire Katie Weston and is a great project for a new knitter. This headband will keep you cosy in the chilly weather, it’s simple to knit, and is a great use for small amounts of handspun yarn. The smaller thickness of fabric at the back of the head means the headband stays in place when you move your head.
The pattern is really simple, all knitting, no purls, increases using knit front and back, and decreases using knit 2 together. To create the button hole you use a yarn over.
If you can’t knit there are lots of local classes and knitting groups all over the country and knittinghelp.com has lots of free videos to get you started.

All our patterns have been generously donated to the project by MSF supporters and are available for your knitting pleasure. In return, we ask that you make a donation to p/hop based on the hours of enjoyment you will get from knitting these patterns.
