Build a two-color grid
Reduce an image to two chart colors and assign alternating row colors.
Mosaic Crochet Pattern Maker
Create an editable two-color overlay mosaic crochet chart from an image or sample. Review the alternating row colors, marked motif cells, row-by-row positions, and color totals, then print the chart.

Features
Explore what this workspace can do, how each control affects the result, and which export fits your next step.
Mark motif positions
The grid distinguishes motif cells from background cells and lists their column positions by row.
Edit and count
Paint the chart, inspect position totals, and review the row sequence.
Print a chart reference
The printable result is a color-position chart; it is not a complete written crochet pattern.
Create a two-color overlay chart
Use an image as a motif source, edit the marked positions, and verify the chart against the overlay method you use.
Load a motif
Start with the sample, upload a local image, or enter a simple text motif.
Choose the two colors
Select the base and motif colors, then adjust the chart width.
Check rows and print
Review alternating rows and marked positions against your chosen technique.
What this two-color chart represents
Rows alternate between two selected colors, and marked cells identify the motif positions for the overlay chart. The row list makes those positions explicit rather than relying on color alone.
The chart does not generate a complete stitch sequence or confirm how a particular overlay or inset method handles edges and turning rows. Check the chart with the technique and notation you plan to use.
Simplify the source before following the rows
A small chart can merge detail and produce isolated color changes. A clear silhouette and limited color regions are easier to inspect row by row.
Edit the marked positions before printing and verify the row count, color order, and chart width in the tool. Your gauge determines the finished dimensions.
Mosaic crochet pattern maker questions
How does the mosaic crochet chart work?
It displays a two-color grid with alternating row colors and marked motif positions. The row list names those positions explicitly.
Does the tool create a complete mosaic crochet pattern?
No. It creates an editable chart reference, not full written stitch instructions. Check row construction, edges, and turning details against your chosen technique.
Can I convert a photo into the chart?
Yes. Upload a PNG, JPG, or WebP image to create a two-color motif grid in your browser.
Can I change the two colors?
Yes. Choose the two chart colors and paint positions to refine the motif.
What does a marked cell mean?
It marks a position in the motif color for the current chart. Confirm how that marker maps to stitches in your chosen overlay method.
How do I read the row list?
Rows are numbered from top to bottom; each row shows its color and the chart columns marked for the motif.
Can I print the chart?
Yes. Print view includes the grid, alternating row colors, row labels, and the color key.
Can I edit the chart after conversion?
Yes. Paint or erase chart cells. The preview and row-position list update immediately.
Does the chart include gauge or finished dimensions?
It shows row and column counts. The current editor does not estimate dimensions because stitch gauge varies by yarn, hook, and technique.
Does the tool save my photo or pattern?
No. Image processing and edits remain in the current browser session. Download or print the chart before leaving.
