Welcome to Closet Core Patterns

I’m Heather Lou, founder of Closet Core Patterns. I started sewing because I was in debt up to my eyeballs from shopping, I was bored and unfulfilled at work, and I was desperate for a creative outlet. Little did I realize how learning to sew would forever change the course of my life.

We’ve grown from a one-woman show in my Montreal apartment to a thriving small team who are as ardent about sewing, creating, and learning as I am.

I invite you to explore our elevated sewing patterns and rich content library filled with sewing classes, video and blog tutorials, and so much more.

Regardless of where you are on your own sewing journey, I am so happy you’re here. I hope you too are making beautiful things, and learning something new about yourself every time you sit down to sew.
