Original Overlay Mosaic chart library
Free Mosaic Crochet Patterns
Open an original Overlay Mosaic chart, inspect its X markers and row instructions, then download the same editable chart as a free PNG or PDF. Every card is a two-color Overlay Mosaic document validated by the current rules; it is not an inset or interlocking Mosaic claim.

Every card is a live, algorithm-validated Overlay Mosaic chart. Open a copy to edit colors or cells; source seeds remain unchanged.

Read the actual chart before you download
Each card shows its live chart, palette, repeat when one is defined, and the same row data sent to the export. X marks a drop-down Mosaic double crochet; unmarked cells use the documented background stitch for that row.
Customize without changing the source library
A template opens as a fresh local working document. You can recolor it or edit cells, but the original seed remains unchanged for the next visitor. Export remains free and requires no account.
Validation is not a physical test-crochet claim
The charts pass the software Overlay validator. They are labelled honestly as algorithm-validated and are not represented as test-crocheted finished objects. Check your own gauge and tension before planning yardage or a final size.
