"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.

Hi! I'm Jenny Rushmore, the blogger, sewing pattern designer and teacher behind Cashmerette. Learning to sew transformed my body image, and my life's passion is helping other curvy women find their body confidence, too. I work with professional pattern-makers to create fashion-forward designs in sizes 0 - 32, and bust sizes C - H, and teach women how to get a fantastic fit in their self-made garments. I believe that your dress size doesn't limit you creativity, so why should it limit your wardrobe? If you want to learn more, check out my blog at Cashmerette.
