"Jenny: thank you so much for making this online workshop. Many things I knew intuitively from my years of sewing, but many I DID NOT. What an incredible source of information you are. Now I can feel comfortable doing my own alterations to make the garment "mine". A truly clear and very informative workshop."

-Pamela R.

We’ll be working with the Cashmerette Springfield Top, a simple woven tank designed for curves, and you’ll learn how to draft and sew 10 new garments.

  • A button-back or button-front blouse
  • A cross-over back top
  • A back keyhole top with a neckline facing
  • A V-neck top with an all-in-one-facing which covers the neckline and armholes

Hi, I'm Jenny! I founded Cashmerette because I was so frustrated with never being able to find clothes that fit my plus size, curvy body (hello, H cups!).

I learned to sew at the tender age of 30, excited by the potential of being able to make clothes that fit me, and also reflected my bold, print-loving style. But I immediately faced the same issue that I did with store-bought clothes: most of them didn’t come anywhere near to fitting me well, not least because most were designed for a B cup.

So I learned how to alter patterns and had the (literally!) life changing revelation: that I could change my clothes to fit my body, rather than changing my body to fit clothes.

And well, the rest is history! At Cashmerette we have the patterns, books, and workshops that I wish had existed when I learned to sew. This, here, is my life’s mission, and I’m so glad you’re along for the ride!

As for the rest of my life? Well, I live with my daughter just outside of Boston, Massachusetts, but I’m originally from the UK (still have the accent!), and am very familiar with the British Airways Boston-London flight schedules. When I get the time, I also love drawing, painting, and cooking fancy things.
