Wylam is a take on a good ol' ribbed beanie with its knit columns flowing out of the ribbing and into the crown pattern and finally merging together at the tip of the crown.
The pattern is written for two different weights of yarn: Worsted and Bulky and each one comes in 5 sizes from 16 inch to 21 3/4. Some of the sizes of course overlap and some differ from one another as is inevitable when designing something with two different weights of yarn, but the hats have their own stitch counts and measurements that are based on those stitch counts rather than the same instructions applying to both.
Originally we were planning on publishing the hats as two separate patterns but Elizabeth Green Musselman, who was copy editing the book, came up with a clever way to incorporate the instructions into a table to make finding your way between so many sizes easy.
The Worsted sample is knitted in Lorna's Laces Shepherd Worsted, Cedar.
The Bulky sample is knitted in Lorna's Laces Shepherd Bulky, Brick; with each one requiring only one skein of yarn.
