Learn how to use your sloper

A fitting sloper is a basic, closely fitting pattern that you refine until it fits your body really well. Think of it as your personal blueprint. Fit it once, then use it to alter new patterns, or even create new designs that you know will fit you. Learn more about slopers

In Cashmerette Sloper School, curvy fitting expert Jenny Rushmore teaches you how to make your sloper and how to use it, in an online course you can take at your own pace.

Fit once, sew confidently forever!

You will love Sloper School if...

  • You're tired of spending tons of time fitting new patterns when you could be designing or sewing
  • You need to go beyond the "standard" adjustments covered in most books and tutorials
  • You've found it hard to learn to fit alone, and want personal feedback from Jenny and her team
  • You've tried "draft it yourself" slopers and found they don't work well for curvy or busty bodies
  • You like the idea of a custom-fit sloper, but don't know how to use one with other patterns

Hi, I'm Jenny! 👋

My life changed when I learned I could change my clothes to fit my body, rather than changing my body to fit clothes. It radically boosted my confidence as a plus-size, curvy woman.

Now, my life’s mission is to help others discover the transformative power of sewing clothes that fit well, and are authentically you.
