Frequently Asked Questions
A cross-stitch chart is a visual pattern that shows you where to place stitches on fabric. Each square on the grid represents one stitch, and colors or symbols indicate which thread color to use.
Fewer colors (8-16) give a simpler, more classic embroidery look. More colors (24-48) capture fine details and gradients, but may require many different thread shades. Try different settings to see what you like.
Absolutely! Once you generate a pattern, you can download it as a PNG image to print or view on a screen while stitching. The symbols and legend help you follow the correct colors.
High-contrast images with clear edges (like cartoons, logos, or simple illustrations) convert beautifully. Photos with many soft gradients may lose details when reduced to stitches.
Stitch size (e.g., 60×60) means the pattern will have that many stitches across and down. On typical 14-count Aida fabric, 60 stitches equal about 4.3 inches (11 cm).
This tool provides a visual color chart. You can manually match each color block to the nearest DMC thread using a conversion chart or by eye. Future updates may include direct DMC suggestions.
