Implemented
Image to Mosaic Grid
Conversion of source artwork into a crochet-sized working grid with controlled resizing and image processing.
Active Development Project
Building the
Mosaic & Tapestry Generator
A specialised browser-based tool for mosaic and tapestry crochet designers and crocheters is being built step by step at DIYeduc — combining image preparation, chart generation, editing, written instructions and professional pattern exports in one workspace.
Development is ongoing • First public testing version planned for the first half of 2027
The idea behind it
Why I am building this program
Creating a good crochet chart involves much more than converting an image into coloured pixels.
Pattern design still requires a lot of manual work.
Images need to be resized, simplified and cleaned. Important contours must remain readable, tonal areas need to work at the chosen stitch size, colours must be controlled, and the finished chart has to follow the technical rules of the selected crochet method.
Complex designs may require many hours — and sometimes days — of manual preparation and correction.
The Mosaic & Tapestry Generator is being developed to bring these processes together into one specialised environment.
The goal
The aim is to let crocheters prepare an image, generate a usable crochet chart, clean and edit the result, create the appropriate instructions and export a complete pattern from one place.
Not simply a pixel converter — a tool designed around
the practical requirements of real crochet patterns.
Development status
Where the project is now
The basic pattern engine is already working, but a large part of the complete user-facing program still needs to be built.
Overall development progress
Approximate progress for the complete future generator, not only the current backend engine.

Inside the generator
What is being built
Some systems are already implemented, others are currently being developed, and several major functions are planned for later stages.
Implemented
Dithering & Tonal Conversion
Multiple dithering algorithms for retaining useful tonal information while converting source images into crochet charts.
In Development
Smart Pattern Cleaning
Removing unwanted visual noise while preserving useful contours, tonal details and important structural information.
Implemented
CUT & NO-CUT Instructions
Automatic row-by-row written instructions for the two overlay mosaic crochet working methods currently implemented.
Planned
Reversible Mosaic Crochet
A dedicated instruction mode for reversible, double-sided mosaic crochet with its own row logic and written instruction system.
Planned
Left-Handed Mode
Mirrored tables, row directions, arrows and written guidance created specifically for left-handed users.
Implemented
Automatic PDF Export
Printable written instruction documents generated directly from the finished stitch grid.
Planned
Pattern Editor
Draw, erase, fill, select, copy and refine the generated chart directly inside the program.
Future
AI-Assisted Image Preparation
Optional AI tools for simplifying artwork, strengthening contours and preparing images according to the intended crochet dimensions.
Planned
Simulated Crochet Preview
A stitch-aware preview designed to help evaluate how small pixel details may visually merge in the finished crocheted fabric.
Planned
Multilingual Instructions
Independent interface and instruction languages, with English, French, German and Dutch planned first.
Planned
Yarn & Pattern Analytics
Stitch totals, colour percentages, yarn estimates, pattern density, complexity and other useful technical statistics.
Planned
Multi-Colour Patterns
Support for charts using more than two colours, including colour mapping, palette control and multi-colour pattern workflows.
Future
Browser-Based Workspace
The planned user version will run directly in a web browser without requiring a traditional desktop installation.
Planned
Responsive Multi-Device Interface
An adaptive interface for computers, Chromebooks, tablets and mobile devices, with controls designed for different screen sizes and touch interaction.
Roadmap
From prototype to public testing
Development happens in layers. Each major system needs to become reliable before the next stages can be built on top of it.
Stage 1
Core pattern engine
Image processing, resizing, dithering, grid creation, stitch conversion and basic instruction logic.
Largely Implemented
Stage 2
Pattern quality & smart cleaning
Tonal preservation, size-aware simplification, contour protection and advanced pattern cleanup.
Current Focus
Stage 3
Additional crochet systems
Reversible mosaic crochet, left-handed support, multi-colour workflows and expansion of the generator toward tapestry crochet.
Planned
Stage 4
Editor & visual workspace
Drawing tools, manual corrections, tracing, previews, zooming, navigation and a practical editing workflow.
Planned
Stage 5
Browser interface & exports
Responsive browser workspace, tablet and mobile adaptation, presets, multilingual controls and professional export options.
Planned
Stage 6
Community testing
Real-world testing with crocheters, bug fixing, usability improvements and pattern verification.
First Half 2027
A specialised tool
What matters most during development
01
Crochet comes first
Technical decisions need to make sense in the finished crocheted fabric — not simply look good in a pixel preview.
02
Automation without losing control
The program should remove as much repetitive technical work as possible while still allowing the designer to make manual decisions when needed.
03
Real patterns, not laboratory examples
New functions are evaluated using actual crochet artwork containing flowers, animals, portraits, landscapes and complex tonal details.
Optional support
Would you like to support the development?
The Mosaic & Tapestry Generator is an independent project being developed alongside DIYeduc and my pattern design work.
Development, testing, website infrastructure and future online services all require time and resources.
If you follow the project and would simply like to help it move forward, you can make a small voluntary contribution.
There is absolutely no obligation. Following the development and eventually helping with testing are already valuable ways to support the project.
Contributions are voluntary support for the ongoing development project. They are not purchases, subscriptions, pre-orders or guarantees of access to a future product.
Support the Development
Choose any amount you feel comfortable with. Every contribution helps support continued development and testing.
Questions
About the project
Is the Mosaic & Tapestry Generator available to use now?
The program is still in active development. The
current version is an internal development build while
the core systems are being created, tested and
improved.
When will public testing begin?
The current target is to prepare the first public
testing version during the first half of 2027.
Development dates may change depending on technical
progress and testing results.
Will it work on Windows, Mac, Chromebook, iPad, tablets and mobile devices?
The planned user version is browser-based and is
intended to work across desktop computers, laptops,
Chromebooks and tablets, including iPads and Android
tablets. A mobile-friendly interface is also planned.
Some advanced editing tools may naturally be more
comfortable to use on a larger screen, but the
interface itself is being planned with responsive and
touch-friendly use in mind.
Will I need to install software on my computer?
The planned user version is intended to run directly
in a web browser, so a traditional desktop software
installation should not be required.
Will the generator support more than two colours?
Yes. The current development engine is primarily
focused on the two-colour mosaic workflow, but
multi-colour chart generation and palette control are
planned for later development stages.
Will the program work with tapestry crochet too?
Yes, that is part of the longer-term development plan.
Mosaic crochet is the current technical foundation and
the first major focus, while the generator is intended
to expand into tapestry crochet workflows as
development progresses.
Will reversible mosaic crochet be supported?
Yes. A separate reversible double-sided mosaic crochet
instruction mode is planned, with row logic and written
instructions adapted specifically for that method.
Will there be support for left-handed crocheters?
Yes. Left-handed support is planned as a dedicated
option with mirrored reading directions, tables, arrows
and corresponding written instructions.
Will it create a perfect pattern automatically?
No automatic converter can guarantee that every image
will immediately become a perfect crochet pattern.
Image complexity, target dimensions and artistic
decisions still matter. The goal is to automate as
much repetitive technical work as possible while
giving the designer tools to refine and control the
result.
Does making a contribution give early access?
No. Contributions are voluntary support for the
development project. Testing invitations and future
access arrangements will be announced separately when
the project reaches that stage.
