What Kate does

🖼️

Any image into a pattern

Photos, cartoons, drawings, artwork — Kate matches your image to real drill colours using perceptual (CIELAB) colour matching, for true-to-life results.

💎

The full DMC palette

All 454 DMC colours are built in, so every drill in your pattern maps to a real colour code you can buy.

✨

Automatic cleanup

Smart confetti reduction tidies away scattered stray drills, so your pattern is calmer and far more pleasant to work.

🖌️

Edit by hand

Zoom right in and recolour individual cells — fix a stray colour, sharpen an edge, make it exactly how you want.

🖨️

Two ways to print

A clear, readable working chart to follow as you go — or a true-size print-at-home kit to lay your drills on directly.

📄

Print-ready PDF

Clear symbols, a colour legend, and drill counts for every colour — printed true to scale, so you know exactly what to order.

How Kate works

From your picture to a pattern you can print, step by step.

Convert almost anything

Start with any photo, drawing, cartoon or piece of artwork. Kate turns it into a diamond painting pattern, matching each colour to a real DMC drill for true-to-life results.

Choose your size

Decide how big your finished piece will be. As you adjust, Kate shows the finished dimensions and exactly how many drills you'll need.

Automatic cleanup

Kate tidies away scattered single drills — the “confetti” that makes patterns fiddly — so your pattern is cleaner and much easier to place.

Choosing how many colours the pattern uses

Dial in the colours

Choose how many colours your pattern uses: fewer for a simpler, bolder look, more for fine detail.

Kate on the big screen

Samsung DeX lets you plug a Samsung phone into a monitor or TV and use it like a desktop, with a mouse and keyboard — so you can see your pattern on a large screen and edit comfortably while your phone does the work. You don't need it, but it's lovely for detailed work.

The printed output

Kate gives you two kinds of printout, so you can work the way you like.

Working Chart

A chart to read while you craft

Enlarged symbols that are easy to follow as you work. It isn't the finished size — you read from it and place your drills on a separate canvas.

True-Size Kit

The pages become your canvas

Printed at the real finished size. Print the pages, apply a double-sided adhesive sheet, assemble them, and place your drills straight onto the grid — just like a shop-bought kit.

Tip: print at 100% / Actual Size (not “Fit to Page”) so your drills line up.
