For anyone wanting to sew rugged, menswear-inspired garments.

Thread Theory Designs is an online sewing pattern and supply shop based on Vancouver Island, B.C. We ship worldwide and our Thread Theory pattern line can be found in hundreds of haberdasheries internationally. We want to help you acheive your menswear and menswear-inspired sewing goals!

Our Mission

We began Thread Theory in 2012 with a mission to bring menswear sewing patterns to the forefront of the DIY fashion movement. We have since expanded into androgynous workwear sewing patterns. Along with our extensive Thread Theory pattern line, you will also find a comprehensive catalogue of menswear and workwear patterns from other pattern designers as well as a curated selection of rugged notions and tools in our shop.

We're happy to meet you!

Morgan Meredith

The co-founder and leader of our little pattern company. Morgan has a background in fashion design and a passion for practical clothing and simple living. She designs our pattern line, is the person you'll chat with when you contact us, and curates our shop.

Our talented pattern development manager. She creates our detailed instruction booklets and accurate illustrations. She orchestrates communications between the rest of the pattern development team. In addition to this, Adrianna shares her passion for and expertise in sewing on our social media platforms.

We don't work alone!

Thread Theory wouldn't be possible without the enthusiastic and talented support of our family (or should I say models), Gwen Lutz (our very precise patternmaker), Sonia Bishop (sister-in-law and graphic designer), and the entire Thread Theory community who help and inspire eachother as they sew. Thank you!
