Leather Tube Bag Pattern – DIY Cylinder Shoulder Template

Leather tube bag pattern for artists, crafters & creators

This leather tube bag pattern is for those who carry more than just everyday things. It’s for rolled canvases, architectural drawings, woodcarving tools, long brushes, leather straps — the kind of gear that doesn’t fit into standard bags. With its solid cylindrical structure and vintage look, this bag feels like something from a workshop or an old atelier. And that’s exactly the feeling I wanted to capture.

Materials you will need

For the main details, use leather that is 2–2.4 mm (5–6 oz) thick.
For additional elements, use leather that is 1.4–1.6 mm (3.5–4 oz) thick.

Hardware required for the Leather Tube Bag Pattern:

• Rivets – 40+ pcs

Designed for people who work with their hands

This isn’t a casual fashion accessory. The DIY leather cylinder bag template is made for professionals, artists, and makers who carry real tools. Whether you’re heading to a studio, a fair, a site, or an open-air workshop — this tube keeps your long-form essentials protected and organized.

You can carry it by the top handle or attach the shoulder strap with snap hooks. The locks close tightly, and the structure feels solid. You’ll immediately feel like you’re carrying something important — because you are.

Vintage hardware meets modern practicality

The three metal locks on the top are more than decoration. They give the piece its vintage soul, like something you’d find in an old craftsman’s shed or an architect’s bag from the early 1900s. Combined with thick leather and hardware detailing, the bag looks serious — and it is.

Whether you’re transporting rolled sketches, training weapons for cosplay, specialty tools, or handmade goods, this leather shoulder tube bag makes a statement.

Customize your handmade leather tool bag pattern

This project lets you explore structure and shaping like few others. Reinforcing the body with rods, securing it with Chicago screws, balancing form and function — this is not a beginner-level concept, but it’s worth the time.

You can finish it in raw leather for a workshop look, or polish it to elegance for a high-end statement piece. Either way, the handmade leather tool bag pattern becomes your own.
