Custom Diamond Painting Patterns: How to Create Your Own from Any Photo
Why Make Your Own Diamond Painting Pattern?
Custom diamond painting kits from companies like Diamond Art Club or Paint With Diamonds cost $50–$150+. The markup is enormous — the actual diamonds cost pennies, and the pattern is just a printed canvas. By generating your own pattern, you can: use any image you want (not just their catalog), control the size and color count exactly, avoid the common complaint of wrong colors in shipped kits, and save 70%+ by buying diamonds separately. The trade-off is you'll need to print the pattern yourself and sort your own diamonds, but many diamond painters prefer this because they get exactly what they want.
How Diamond Painting Patterns Differ from Cross-Stitch
Diamond painting uses a fixed grid density — approximately 2.5 drills per centimeter (equivalent to 10-count in cross-stitch terms). You can't change this because the adhesive canvas has a fixed grid. This means diamond painting patterns are inherently lower resolution than cross-stitch. A 30×40cm canvas gives you about 75×100 drills — that's 7,500 total cells. For comparison, a cross-stitch pattern on 14-count Aida at the same size would have 118×157 stitches (18,500 stitches). This matters for image selection: diamond painting needs simpler, bolder images because there are fewer pixels to work with.
Round Drills vs Square Drills
Round drills are easier to place and more forgiving — small gaps between drills are less visible. They're ideal for beginners and images with lots of gradients (like portraits and landscapes). Square drills cover the canvas completely with no gaps, giving a mosaic-like finish that looks sharper and more polished. They require more precision to align but the result is more impressive. ArtPatt lets you select drill type in the pattern settings. The choice doesn't affect the pattern itself — it's the same grid either way — but it's noted in the PDF export for reference when ordering supplies.
Finding the Right Color Count
Diamond painting kits typically use 20–45 DMC colors for a standard design. More colors means more detail but also more sorting, more small bags of diamonds to manage, and more confusion during placement. For a first custom project, 15–25 colors gives excellent results. Pet portraits usually need 20–30 colors to capture fur detail. Simple graphic designs or cartoons work great with 10–15. Abstract art can get away with 8–12. Each color maps to a DMC code, which means you can order exact diamond colors from suppliers like Diamond Drills or Amazon using the codes in your pattern's color legend.
Choosing Photos That Work Well
The lower resolution of diamond painting means image choice matters more than any other craft. Best results: close-up portraits with a simple background, bold graphic designs with clear shapes, landscapes with distinct foreground/sky separation, and pet photos with good lighting. Worst results: group photos (faces too small), busy backgrounds with lots of tiny details, very dark images, and photos with subtle color gradients (they'll become blocky at 10-count resolution). Before generating, use the brightness and contrast sliders to boost your image — diamond paintings look best with slightly exaggerated colors.
Confetti: Even Worse in Diamond Painting
Confetti drills — isolated single-color placements scattered throughout the canvas — are even more annoying in diamond painting than in cross-stitch. Each one means finding a different color bag, placing one drill, putting the bag away, finding the next color. With 30+ colors and hundreds of confetti placements, it can take hours of frustrating work. ArtPatt's confetti reduction is essential here. Set it to 'Heavy' for diamond painting — the visual difference is minimal at 10-count resolution, but the time savings are enormous. After generating, check the confetti percentage. Aim for under 2% for a pleasant diamond painting experience.
Sizing Your Canvas
Diamond painting canvas size is determined by the grid dimensions and the fixed 2.5 drills/cm density. A 50×75 grid gives you a 20×30cm canvas (about 8×12 inches) — a good starter size. For a statement piece, go 80×100 or larger (32×40cm). ArtPatt's dimension display shows exactly what size your finished piece will be. Most diamond painting suppliers sell blank adhesive canvases in standard sizes, or you can order custom-cut canvas. When ordering diamonds, the color legend tells you exactly how many of each color you need — multiply the stitch count by the drill size to estimate bags needed (typically 200 drills per bag).
Printing Your Pattern onto Canvas
The PDF export includes everything you need: a symbol chart where each cell has a unique symbol per color, a color legend mapping symbols to DMC codes, and drill quantity estimates. For diamond painting, the symbol chart is what you print or reference. Some crafters print the symbol chart on paper and place it next to their canvas. Others use a tablet to zoom into sections. If you want to transfer the pattern directly onto adhesive canvas, use the symbol-only (B&W) mode — it prints cleanly on any printer and the high-contrast symbols are easy to read through clear diamond painting pens.
Where to Order Diamond Painting Supplies
With your pattern's DMC color list, you can order from multiple suppliers. Amazon sells individual DMC-coded diamond bags (search 'diamond painting drills DMC [number]'). Specialty sites like DiamondDrillsUSA and AliExpress sellers offer bulk packs sorted by DMC code. Order 20% more drills than the pattern estimates — some will be lost, misshapen, or wasted. You'll also need: adhesive canvas (or a pre-made blank canvas), a diamond painting pen/applicator, wax pad, and a tray for sorting. Total cost for a custom project: typically $15–30 for materials, versus $50–150 for a pre-made kit.
