Yeah, EZ's great. She's responsible for increasing the popularity of Continental knitting, and the popularity of knitting in the round, and knitting seamless sweaters in the round. She also popularized (introduced?) the percentage system, where you figure out how many inches the body of your sweater is, and then work out how many inches wide your sleeves can be, and how high up to put them, and how many inches the neck will be, all based on percentages from the body stitches. It sounds complicated, but many feel this is the easiest kind of sweater to make, and it's very versatile, you could knit a sweater for most anyone, never looking at a pattern again!
EZ put out many books and videos, under her own press, "Schoolhouse Press." Her daughter Meg Swansen, another highly accomplished knitter, runs the company now, and is also published. I just talked to Meg for the first time, recently, over the phone, and she's INCREDIBLY NICE and just wonderful! She runs a knitting camp every summer, which I'm thinking about attending this year!
