Cleaner Patterns, Easier Stitching — Stitch Pattern Maker Update

Stitch Pattern Maker turns your photos into cross-stitch charts. This update has a single keyword: a pattern that's actually good to stitch.

A pretty preview isn't the point. What matters is whether you can sit down at the fabric and stitch it without fighting the chart. So this release goes after the two things that frustrate stitchers most — background speckle noise and colors used for only a handful of stitches.

What changed	Before	After
Background noise	Lone white/blue cells dotted across flat gray	Isolated cells absorbed into neighbors, flat areas kept
Color list	Lots of colors used for just 1–30 stitches	Barely-used colors merged into their closest match

1. We cleaned up the background "confetti"

You've probably seen it: a single white or sky-blue cell sitting in the middle of a flat gray background. That's isolated single-cell noise (confetti) created during photo conversion. It looks messy — but the bigger problem was hidden.

Those lone cells survived into the color-matching step as "orphan colors," quietly eating up palette slots. That left fewer colors for the subject that actually matters.

So before the colors are finalized, we now sweep the chart grid once and gently absorb any cell that's out of place into its neighbors. The key is that it stays conservative — only truly isolated cells get cleaned up, while intended detail like the fine lines of a cat's fur is preserved.

2. Fewer "buy a whole skein for one stitch" moments

Charts often came back stuffed with colors used for just 1–30 stitches. For a stitcher, that's the worst case. They look like dust on screen, and to buy a kit you'd have to purchase a full skein for a handful of stitches.

Right after color matching, we added a final pass that automatically merges barely-used colors into their closest match. Color distance is measured with CIEDE2000, tuned to match human perception, so colors fold into the most natural neighbor instead of getting pulled toward something off.

The result is a shorter, cleaner color list and a lower real-world cost to buy and stitch. From the same photo, you get a tidy palette with the throwaway colors removed.

Bonus: a browser tab icon

A small missing detail, now filled in. Browser tabs, mobile home screens, and PWA installs show a dedicated icon (a cross-stitch heart).

What's next: smoother gradients (experimental)

We're also experimenting with error-diffusion dithering to make gradients read smoothly even with few colors. But this technique can increase scattered single-cell color changes and make stitching harder, so we won't ship it until it passes testing on actual fabric. Quality is decided at the needle, not on the screen.

Wrapping up

This update focused less on flashy features and more on one question: can you trust the chart you got and just stitch it? A cleaner background, a tidier color list — small changes, but ones that make a real difference in your actual working time.
