Thanks for your enthusiastic response to the Summer Sweater KAL, here and on Ravelry! I’m crazy excited to get started on my tank, but first I need to finish this:

Luckily, the schedule at Squam seems to build in a lot of down time, so I’ll have some nice quiet hours this weekend to work on the stripes when I’m not teaching.
But before I head off for the weekend, I wanted to talk a little bit about a question I get a lot, in classes and email. Many of you might know that I recommend a smidge of negative ease in the hips. When I say so, in class, I frequently get this in response:
I’m nervous about having any negative ease in my hips. Won’t that just look too tight, or be uncomfortable?
The answer is: No, at least not in the amount that I recommend. Let’s take a closer look.
What is negative ease?
Ease refers to the difference (if any) between what your body measures and what a garment measures, somewhere on your body. The overall ease of a sweater doesn’t exist, because well-fitting sweaters fit you one way in your shoulders, another in your bust, a different way in your waist, etc.
How much do you recommend?
For an average-length sweater (i.e., one that doesn’t go below the curve of your bum), I recommend an ease range of -3” to +2”. That means the sweater will measure somewhere in between 3” smaller than your hips, and 2” larger than your hips.
What does that look like?
Let’s start with the negative end of the range. Truly, a little bit of negative ease is a really attractive look. It doesn’t look too tight, it isn’t uncomfortable to wear, it just looks like it fits:

All of these garments have between 3” of negative ease, and zero ease, in the hips. This negative ease represents far less than 10% stretch for most people, which is literally nothing when you’re talking about a hand knit fabric. And yet, this amount of negative ease is functional: It helps keep the garment in place on your hips, letting you move your arms and torso without the sweater slipping all around on your body.
Some sweaters want to look more relaxed than this, of course. If you’d like a roomier look, I’d suggest between 0” ease in the hips and just 2” of positive ease in the hips. Here’s what that looks like:

Why shouldn’t I make a sweater even roomier than that?
If you go beyond 2” of positive ease in the hips of an average-length sweater, it will float, UFO-like, outside your body. This is a fairly strong visual cue that your sweater doesn’t fit, and most people react poorly to it when they see the sweater on them. (And note: All of this goes out the window for long sweaters that go down to or past the bottom of your bum. You need positive ease in those sweaters, to ensure the garment doesn’t cup underneath your bum!)
Whatever look you prefer, to ensure that the sweater looks like it fits you well, I definitely recommend a -2” to +2” range. I hope these pictures have helped make things a little more visually clear – and that your knitting is going well and you’re excited about summer. See you on the flip side of Squam!
