Collection: Project Patterns

21GRAMS Project Patterns are downloadable leathercraft templates for building real finished goods.

The standard is simple: if the pattern does not build correctly, it does not get released. Each project pattern is test-built before publication so dimensions, fit, assembly, and construction make sense in actual leather.

Practical leathercraft templates, not guesswork

Project patterns are created for wallets, accessories, cases, and other leather goods, with the goal of giving makers a repeatable path from digital pattern to finished project.
