Heather Lou // Sewing blog author and owner of Closet Case Patterns


Hi, I’m Heather Lou! Perhaps like you, I was once overwhelmed by the prospect of sewing. A creative-minded, fashion-obsessed interior designer getting paid to design commercial spaces, I was supposed to be living my dream… but in reality, I had finally reached a tipping point. My closet was crammed with ill-fitting clothes I didn’t wear, my credit card was maxed out from too many shopping sprees, and I didn’t feel connected to or creatively inspired by my wardrobe.

I knew I had to get radical. I pitched myself a challenge: for one year, the only new things that would enter my closet would be things that I made with my own two hands. It was terrifying, a little extreme, and… the best, most life-altering decision I ever made, hands 100% down. I gave myself permission to go back to basics and find what really worked for me, and sewing became the centerpiece of my entire life. Every time I threaded a needle or pressed a piece of fabric, I felt myself making a tangible, tactile connection to my clothes and my innate creativity. Sewing felt revolutionary and expressive, a technical skill and a timeless art form rolled into one. I could make anything I wanted to when I sat down to sew, and I could make things that no one else in the world could own. Somehow, that became so much more chic than just buying the Next Big Thing.

That year, I started with a vintage dress and soon worked my way up to the more complicated stuff. A few months in and it was clear that I was addicted to this act of rebellion against aimless spending, unsustainable manufacturing, and one-size-fits-all design. I had begun to fill my closet with pieces and patterns that were made by me, fit my body perfectly, and spoke to me in a way that the ready-to-wear pieces I used to hoard never did. For the first time, I respected my clothes and they respected me. I tailor-made what fit my body, instead of expecting it to fit into an arbitrary mold created by the fashion industry. Sewing became the positive feedback loop that I couldn’t stop thinking about and the creative outlet that I desperately needed.

The hours I spent in front of my sewing machine made it more and more clear that my part-time passion had outgrown my full-time profession. Frustrated that I was contributing to mindless consumption in a bankrupt consumer culture by designing shopping centres for a living – and mindful of the pressing need for chic sewing patterns and clear instructions for the modern sewing movement – I made the decision to launch Closet Case Patterns as a full-time business.

These days, I’m a professional sewing enthusiast and advocate that transforms your imagination into implementation, breaking down the step-by-step in Plain English to help you create pieces like luxurious caftans, jeans designed for every body, and figure-flattering swimsuits that make everybody feel great at the pool. My mission is to create timeless, fashionable patterns that can be customized, personalized, and hacked with your own vision and unique touch.

Like the practice of sewing itself, Closet Case Patterns is an ever-evolving business that blends my own love of craft and community. I hope that through reading my own story, you’re inspired to fearlessly eliminate what no longer serves you – and embrace a lifestyle of personal expression that fits you like a glove.
