Transformer Leather Bag Pattern – Crossbody Base Model

A bag that transforms with every mood

When I created this Transformer leather bag pattern, my idea was simple – one bag, many looks. This crossbody base model is the foundation: a stylish and practical bag with two pockets and a replaceable flap. Thanks to Chicago screws, the flap can be changed in minutes with just a screwdriver. That means no need to sew a new bag every time – I can keep the same body and refresh the style with a new design.

Materials I used

For this base model, I worked with leather 1.6–2 mm (4–5 oz) thick. I chose vegetable tanned leather and dyed it with leather dye to get the color I wanted. Here’s the list of hardware that completes the project:

• Rivets – 3 pcs

• Chicago screws – 5 pcs

• Magnetic purse lock – 1 pc

• Buckle – 1 pc

• Snap hooks – 2 pcs

• Steel D-rings – 2 pcs

The bag strap in the pattern is 2.5 cm (0.98 in.) wide, making it comfortable and durable for daily wear.

Size of the finished bag

The finished crossbody bag has dimensions that are compact yet useful:

• Height – 22 cm (8.66 in.)

• Width – 20 cm (7.87 in.)

• Depth – 5.5 cm (2.16 in.)

It’s the perfect everyday companion – enough room for essentials like a phone, wallet, and keys, while keeping a slim profile.

Why this pattern is special

The biggest advantage of this design is flexibility. Once the base model is made, you don’t need to start from scratch again. You can simply change the flap and enjoy a new style without spending extra leather or hours of work. It’s a system that grows with you.

For me, working with leather is about creativity. That’s why I wanted this project to also be a DIY leather bag template that encourages experimentation. You can use classic leather for an elegant result, try bold colors, or decorate with stamping and carving. Every bag becomes a one-of-a-kind piece.

This leather crossbody bag pattern is practical for everyday life. The bag works well for casual city walks, stylish evenings out, or even as a meaningful handmade gift. And because it comes as a printable bag pattern PDF, you can easily print the templates at home and start crafting right away.
