Toy Pattern Builder

Сrochet pieces library

Users can mix and match toy crochet pieces on a canvas. Different-sized amigurumi heads, ears, bodies, arms, wings, legs, and tails, all are designed to be proportional and easy to make.

Toy constructor

After a user chooses a crochet piece and drops it on the canvas, the app combines it with other elements to create a multilayer image. Patterns are split into individual pieces, from ears to paws. Users can mix and match amigurumi pieces to create a toy, choosing types and changing colors.

Crochet instruction generator

A PDF instruction is automatically created after saving the toy design. Users can access a free crochet guide to turn their pattern into a toy. Additionally, a premium version with illustrated additions is also available.

Save point

Users can return anytime to the crochet pattern generator to adjust the layout, update the crochet pieces, or change the colors. The saved design is accessible by the link and can be shared.

Admin Dashboard

Asset library / Responsive design / SVG implementations
Users can access the admin dashboard and perform the following actions:
