A Traditional Pi Shawl ~ Elizabeth Zimmermann
This workshop style class will teach you the basics of circular shawls, this being a Pi shawl.
“Make it simple. For many knitters, this shawl has been an introduction to lace knitting and to the knitting of circular things. And a good choice it is. The lace patterns are not too difficult, and the circle’s shaping is simpler yet. But all can be even simpler.”
Yardage is not listed, weight is given as follows:
“9 oz fingering- (or 12oz sport-) weight Shetland wool”
From the Knitter’s Almanac (July) book:
Summary: A circular shawl based the geometry of Pi–the relationship between a circle’s circumference and its radius containing six shaping rounds.
