Our Materials
Waxed Canvas
A densely-woven cotton fabric that's saturated with wax, giving it protection against the elements. It shows scuffs and creases that blend into a weathered patina. *fabric colors vary in weight from 10-12oz
Leather
Sourced from Oregon and a Pennsylvania tannery, and hand-selected for quality. Our hides are cut into straps with a hydraulic press to ensure precision and consistency.
Hardware
Hardware takes a bag from looking homemade to professional—and it's not hard to do! Using basic tools, you can set rivets & more. All our hardware is real metal and built to last.

😍 Maker Stories
"Finished up another heavy duty canvas bag! I learned a lot of new sewing techniques while making the Portsmith Tote. Definitely recommend! 😄"
"I absolutely love The Porsmith Tote! It fits so much, including my big ol’ laptop, and it was a blast to work with waxed canvas for the first time."
"Oh my gosh the Portsmith Tote really is a beginner-friendly pattern! It only took me a couple of hours to make and I'll definitely be making more. It would make the perfect gift!"
"First waxed canvas and envelope corner experience -anyone who thinks they can't do this— you totally can (it's only two pieces of fabric plus hardware)! Brilliant, beautiful, highly functional, and in my case, burgundy. What's not to love? ❤️🧵✂️👜👍"
"Highly enjoyed making this for mi madre. Waxed cotton on top, with a navy canvas base and leather straps. I'm learning that I really like hammering hardware/rivets. Maybe I should take up kickboxing?!"
"As you’ve surely seen by the piles of totes I’ve been churning out this summer, I am quite a fan of this bag design... The envelope fold at the bottom is my absolute favorite method for boxing corners. It’s simple yet sturdy and just the cutest."

Online Class
Learn to make your Portsmith with Ellie, the pattern's designer, from the comfort of your home sewing machine. The online class is great for visual learners and those who could use an extra boost of confidence.
FAQS
Questions about the Portsmith? We've got you covered.
Yes, you can totally make this bag on a regular home sewing machine! No heavy-duty or industrial machine required. For best results, we highly recommend working on a machine that has been well-maintained and using a new, sharp needle. Denim needles or nonstick needles (if working with waxed canvas) are our favorite!
The Portsmith Tote is a Beginner-level bag making project. The finished bag may look hella professional, but don't let that intimidate you! Even if you've never sewn before, you'll do great. Be sure you have all of the correct tools on hand, and we also highly recommend signing up for the Portsmith online class, as Ellie's video instructions are super helpful for visual learners and anyone who could use an extra post of confidence.
These are the tools and sewing supplies we recommend having on hand for the optimal Portsmith-making experience.
Sewing Supplies:
- Size 100 denim needle or nonstick needle (our favorites for sewing heavy-duty fabric & waxed canvas)
- Craft clips (for securing multiple layers of waxed canvas)
- 5" x 20" Quilting ruler (comes in handy for marking boxed corners)
- Hammer + hard surface (for setting rivets)
Tools:
The Portsmith Tote has double-cap rivets, which can be set with just a regular hammer. Optionally, you can use a double-cap rivet setter and a (non-rubber!) mallet on a hard surface, such as a slab of stone, metal anvil, or concrete floor. To make holes in fabric you’ll need a 3/32” drive punch, which is used with a mallet on a punching board. Or you can use a tapered tailor's awl to make holes in your fabric.
You can add these tools to your kit, or combined in The Drive Punch Toolkit for a discounted price!

The making time for beginner projects is estimated at 1-3 hours. Having said that, each maker has their own pace and process. We recommend adding the online class for extra support and to ensure a seamless (no pun intended 😉) making experience.
We recommend using a 100 denim needle or a non-stick needle, and 2 spools of all-purpose thread to match the exterior fabrics.
The zipper closure and lining expansions are an awesome way to level up your Portsmith Tote. The zipper keeps your stuff secure, while the lining adds structure and a fun pop of color or print to the inside of your bag.
The Portsmith Tote is the ultimate teaching pattern for beginner bag makers, so it's a great project on its own. But if you're ready for a confident beginner challenge, the expansions are a perfect way to up your game.
The expansions do mean juggling two sets of instructions and tackling more advanced techniques, like installing a zipper. But with the included video-guided instructions, you've got what you need to make a tote that's 100% you.
Haven't tried it yet but the wax canvas is nice
I Love this tote, material is soft, not greasy, sews beautifully, looks amazing! Not hard to punch through with the black tool.
I will be using this material again, class was great with clear concise step by step instruction, too. Leather for the handles is soft and pliable and I Love it.
I want to try the other patterns now. Great experience.
Klum House makers kit is great! It is a lovely first project that produces a gorgeous tote. The kit instructions are really good and I was able to follow along easily. All the materials and pieces to do the kit were suggested and included and it was fun to open the package and see all the bits and bobs and get started. The waxes canvas makes a really nice bag and it is easy to work with. I didn’t use the pattern since the kit comes with pre cut material. But I am going to use the pattern to try another bag from other materials - the pattern is well marked so I think it will be straight forward. I really love my new tote and can say Klum House is top notch and high quality.
