There is something incredibly satisfying about carrying your tools in a bag you made yourself. This isn’t your average flimsy tote; this project features a structured design with a wood-reinforced bottom, ensuring it stays stiff and upright even when loaded with heavy wrenches and hammers. With a variety of pleated pockets on both the inside and outside, you can customize your organization for everything from small screwdrivers to larger power tools.

One of the standout features of this project is the clever pocket layout. By staggering large and small pockets on opposite sides, the design avoids excessive bulk at the corners—a common challenge in heavy-duty sewing. To achieve this professional look, we use techniques such as double hems and basting for precision. You’ll also learn how to reinforce stress points with heavy reversing to ensure the handles and pockets won't fail during use.

Because this project uses thick 18 oz. Cotton Duck and multiple layers of webbing, it’s the perfect time to fire up your Sailrite® Ultrafeed® Sewing Machine. A standard home machine will likely struggle with the thickness of these seams, but the Ultrafeed powers through the heavy fabric and webbing with ease.

Key Supplies for Success:

  • 18 oz. Cotton Duck Fabric: This heavy-duty material provides the classic "canvas bag" durability.

  • SewReady® Seamstick Basting Tape: A "must-have" for this project to keep those pleated pockets perfectly aligned before you hit the needle.

  • Webbing: High-quality webbing handles are integrated deep into the bag body for maximum lift capacity.

  • 1.5" Grosgrain Binding: This adds a clean, finished edge to the internal seams for a look that matches the bag's performance.
