Transformer bag pattern heart design panel

A colorful heart for your Transformer bag

Transformer bag pattern heart design turns a simple crossbody into a symbol as much as an accessory. Rooted in the rainbow colors of LGBT pride, the heart speaks of love, freedom, and diversity—yet it isn’t limited to those hues: dye it in any palette you like, from soft pastels to bold contrasts. This flexibility keeps the look personal and playful. Thanks to the Transformer system, you don’t need to sew a new bag each time—just swap the front flap with Chicago screws and your crossbody transforms in minutes.

Materials I used

For this heart design panel, I worked with vegetable-tanned leather without a finish, 1.4–1.6 mm (3.5–4 oz) thick. I dyed the leather in bright rainbow colors to highlight the LGBT-inspired heart. Of course, you can also choose your own palette – from bold contrasts to gentle pastel tones.

Size of the finished flap

This heart design is made to fit the Transformer base model bag with the following dimensions:

• Height – 22 cm (8.66 in.)

• Width – 20 cm (7.87 in.)

• Depth – 5.5 cm (2.16 in.)

It can also be adapted to another bag of similar size if you already have your own crossbody model. This makes the pattern flexible for different projects.
