In this class, you’ll learn to create the Portsmith Tote with Ellie Lum, the founder and pattern designer at Klum House. The Portsmith is a minimal, workhorse of a tote that will quickly become your everyday go-to. With sturdy leather straps, metal rivets, and a reinforced base, the Portsmith is definitely a cut above your average tote bag. It's also a perfect project for beginners looking to dive into bag making for the first time.

This class will help you build a solid foundation of bag-making skills. You’ll learn to work with heavy-duty materials like waxed canvas, leather, and metal hardware to make a professional-quality bag—all on your home sewing machine! If you have some basic sewing experience under your belt and are looking to try bag making, this class is for you. Build new skills, get lost in the flow of making, and create a shop-worthy finished product with “I made this!” bragging rights.

Ellie Lum
Ellie Lum

Hi! I’m Ellie.

I've been designing and making bags professionally for over twenty years. In 1998, I co-founded a custom messenger bag company called R.E. Load bags. After years of training stitchers to manufacture bags, I realized that my true passion lies in teaching. I started Klum House, my current business, as a way to invite more folks to work with their hands, make high-quality finished goods, and gain confidence through making.

Klum House bag patterns are informed by my roots in the industrial sewing industry, but I’ve designed them all to be created on a home sewing machine with just a few extra tools for installing hardware. I love teaching makers to harness the full power of their home sewing machine to achieve professional results without industrial equipment. Klum House classes will teach you to work with natural, heritage materials like waxed canvas, leather, and metal.

Sometimes makers take one look at a heavy-duty bag and think, “I could never make that.” But I promise you, YOU CAN! Just because a finished bag looks impressive doesn’t mean it’s hard to make. I’ll break it all down and guide you every step of the way. You’ll be amazed at what you’re capable of!

Do I need an industrial sewing machine to make this bag?

No! All Klum House bags can be completed on a home sewing machine, no industrial sewing machine required. At the Klum House teaching studio, we teach all of our classes on Singer Heavy Duty 4423 sewing machines that generally retail for $130-150. That is to say, you don’t need a fancy, expensive sewing machine to make our bags. If you have doubts about the power of your home sewing machine, test it out! Try sewing through multiple layers of heavy-duty canvas. Sometimes when a project gets especially bulky, we have to use the handwheel to manually sew a few stitches. If your sewing machine breaks a needle, skips stitches, or refuses to feed the fabric, it might not be up for the challenge. But we see lots of different home sewing machines come through our teaching studio that do just fine!

What skill level is this class?

This class is suitable for beginner bag makers--no previous experience required. It's also great for folks who have experience with different types of sewing, like quilting or garments, and would like to learn more about working with heavy-duty materials, like waxed canvas, leather, and metal hardware. If you have a very basic familiarity with a sewing machine and like to work with your hands, this project is for you. Get ready to seriously impress your friends.
