Personalizing with KnitWiz
Make the sweater you want without rifling through thousands of patterns that aren’t guaranteed to fit. KnitWiz patterns and instructions can be personalized to your measurements, your yarn stash, and your style.

Designing with KnitWiz
Designing patterns is easy and fun with KnitWiz visual tools. Whether you begin with a ‘Quick-Start’ design or start from scratch, you’ll end with a sweater you’ll be proud to wear (and no math needed!)

Selling with KnitWiz
The KnitWiz Marketplace is a better way to sell your patterns because you can make money without worrying about sizing (patterns are automatically size-inclusive) or pattern-writing (instructions are automatically generated).

"As a skilled knitter, I understand the importance of gauge, but most of the time, I cannot match the gauge for the intended pattern. Not only is gauge difficult, but the yarn choice and needle choice affects the outcome. The issue of gauge feels completely eliminated. I must still swatch and measure a swatch accurately, but it is worth removing the other factors that get in the way of beginning a project. The software generates confidence at the front end that the project will be successful."

Hi, I’m Catherine Zoller.
Like most great ideas, KnitWiz was born to solve a problem. Since the inception of the written knitting pattern, hand knitters have faced the tedious chore of modifying pattern instructions manually so that the sweater they wanted to knit would work for their body shape. Until now. As a knitwear designer (I’m currently working to complete the TKGA Designer Certification) and software developer with twenty plus years of experience, I decided it was time to use my professional skills to solve the size inclusivity issue.

"It was satisfying to get a sweater pattern that I didn't have to make a lot of changes to and do all the math."
