Color Block Pattern Maker

Turn a graphgan chart into a color block pattern, row by row, for tapestry crochet.

This is a sample chart. Load your own PDF or image in step 1 and it replaces this one.

1Load a graphgan chart

2Frame the grid

Drag the corner dots onto the outer edge of the chart grid, inside the row and column numbers. The overlay lines should sit right on the chart's grid lines. If they drift apart, the stitch or row count is off.

3Check the colors

Each color below is one yarn. Name it after your yarn if you like.

    To fix a square, pick a color with its round button, then tap or drag on the chart.
