Portsmith Expansions PDF

3 reviews


Level up your Portsmith Tote by adding a zipper closure and/or lining! The zipper closure will help keep all of your things securely tucked away throughout the day. The lining adds structure and is an opportunity to add a fun print or pop of color to your bag's interior. These expansion PDF instructions are designed to be used in tandem with the main Portsmith Tote pattern instructions. 



  • Portsmith zipper closure + lining PDF instructions
  • Access to sew-along videos with Ellie

These PDF instructions are designed to be used in tandem with the main Portsmith pattern, which is sold separately. Helpful signposts will guide your making path, letting you know when it’s time to transition from one set of instructions to the other.

PDF Purchasing Info: After purchasing a PDF pattern, you will receive an email with a link to download the digital file and video. You can also access all previously-purchased digital goods at any time by logging into your account in the upper right-hand corner of our site. NOTE: It may not be possible to download a PDF pattern directly to your tablet or mobile device without a download app. We suggest using Adobe Acrobat in combination with a file storage service like Dropbox to download files to mobiles devices.


At Klum House, we pride ourselves in creating patterns that are thoughtful, holistic, and easy-to-follow. We want you to feel fully-supported at every step of your making journey. This is what you can expect to encounter:

Clear Instructions - We are teachers, first and foremost, and as such we know that clear language is so important. We are dedicated to crafting simple, easy-to-follow instructions, so you can forge ahead with confidence.

Helpful Tips + Cautions - Your instructions booklet will be peppered with helpful tips, reminders, and caution moments. We know all of the most common mistakes (because we’ve made them!) and point them out so you can avoid them.

Excellent Illustrations - Our patterns are filled with helpful, technically-precise illustrations. We makers are visual learners! With 3D renderings and transparent layers, we’ll help you conceptualize every stitch, flip, and fold.

Specialty Education - Bag making is different from other types of sewing. It involves working with heavy-duty fabrics, leather, hardware, and tools you may not have encountered before. But don’t worry, our patterns break it all down.

Multiple Making Paths - Whether you choose to make from a fully-prepped maker kit, a leather + hardware kit, or “from scratch,” our patterns are designed to guide you along your chosen path to guarantee a successful make!


The easiest way to get all the supplies you need is by adding expansions to a Portsmith Full Maker Kit. (You'll get the expansion PDF instructions included that way as well, so no need to purchase them separately here!)

Alternatively, you can purchase a Portsmith Zipper Closure Kit, which comes with the ingredients you need—zipper, and leather pieces—in the colors of your choice.

Or you can source and prep all of the materials yourself! Here's what you'll need:

Portsmith expansions

The zipper and lining expansion pattern was easy to follow and I was very pleased with the end result. This really completes the tote project and is worth the extra time commitment.

I found the instructions with the video tutorial link very easy to follow. I’m so glad I added it to my first Portsmith.

Totally worth it

I added both the lining and zipper extension to my Portsmith bag. This was my first recessed zipper and the instruction were very clear. The extension lays flat when unzipped, you hardly know it is there. It does lie lower than I expected. I had added an extra zipper pocket and open pocket on the sides of my lining and in order to access them I have to lift the extension up, so not as easy to access quickly. But the bonus is they are pretty much hidden and I think of what I put in the zipper pocket as much more secure. I think I get much more use out of my Portsmith with the additions. Love love love the result.
