Generate Mosaic Crochet
Patterns from Images
Upload a design, reduce it to 2 high-contrast colors, and get right-side-only overlay mosaic notation: X chart marks, alternating row colors, and written BLO sc/mdc runs.

Mosaic-Optimized Settings
Mosaic crochet has very specific requirements โ here's how to set up ArtPatt for best results.
2 Colors, Maximum Contrast
Set color count to 2. Choose high-contrast pairs: black/white, navy/cream, charcoal/mustard. Boost contrast slider to +40 or higher in preprocessing. This forces the image into sharp, clean two-tone areas that mosaic technique requires.
Stitchability Check
Overlay mosaic cannot place an mdc in the same column on consecutive rows. ArtPatt validates every column and, when needed, makes the smallest number of cell changes to produce workable notation. The exact adjustment count is shown.
Grid Size for Mosaic
Mosaic works well at 40โ80 motif cells wide. The finished row also includes one edge sc at each side. More cells preserve more detail, but bold silhouettes and geometric shapes still translate best.
X Chart + Written Rows
The PDF marks mdc stitches with X and lists every row in actual working order. Blank cells are BLO sc; X cells are mosaic double crochet into the unused front loop two rows below.
How to Create a Mosaic Crochet Pattern from a Picture
Start with a bold picture that can survive reduction to two colors. Logos, silhouettes, geometric motifs, and simple line art work better than photographs with gradients or fine facial detail. Upload the image, set the palette to two contrasting yarn colors, increase contrast, and use confetti reduction until the main shapes are clear.
Choose Mosaic mode and ArtPatt compiles the image for one defined method: right-side-only overlay mosaic crochet in US terms. It adds setup rows, alternates Color A and Color B, marks mosaic double crochet with X, and writes each row as runs of edge sc, BLO sc, and mdc.
If two consecutive rows would require mdc in the same column, the later stitch would have no unused front loop to anchor into. The compiler resolves those conflicts with the fewest possible changes and tells you how many image cells changed. Always crochet a swatch before committing to a blanket; the generator does not produce inset mosaic or other mosaic variants.
Mosaic Crochet Project Ideas
Throw blanket (60โ80 motif cells wide): Use a bold geometric pattern in two high-contrast colors. The generated row list alternates colors on every row and includes one edge sc at each side. Check the in-app yarn estimate, then make a swatch because mdc height and your tension affect both size and consumption.
Coaster set (20ร20 stitches): Perfect beginner mosaic project. Simple diamond or star pattern. Takes 30-45 minutes per coaster. Use cotton cord for heat resistance. Makes great gifts.
Wall hanging (40ร60 stitches): Mounted on a dowel rod. Geometric mandala or southwestern pattern. Add fringe at bottom for extra length. Frame with a simple wood rod at top and bottom.
