What Is Diamond Painting?
Diamond painting is a craft that combines elements of paint-by-numbers and cross-stitch. You work from a canvas printed with a color-coded grid, and your job is to place small resin diamonds — called drills — into adhesive squares on that grid. When the canvas is filled, the finished piece resembles a sparkling mosaic.
Despite how impressive the results look, the core skill required is simply patience. Each drill goes into exactly one spot, guided by the symbol printed beneath it. There is no artistic interpretation required, which is part of why diamond painting has become so popular with people who love the idea of making something beautiful but feel intimidated by traditional crafts like painting or embroidery.
The craft originated in Asia around 2015 and spread rapidly through crafting communities online. Today it is one of the fastest-growing hobby categories worldwide, with dedicated communities sharing their finished works on Pinterest, Instagram, and Reddit.
The Materials You Need
Most diamond painting kits come with everything required to complete the project. Here is what you should expect to find — and what to look out for if something is missing.
The Canvas
The canvas is a fabric or polyester sheet printed with a grid of symbols. Each symbol corresponds to a color. The canvas is coated with a pressure-sensitive adhesive covered by a protective film, which you peel back section by section as you work. Good canvases feel firm and slightly stiff; low-quality ones may be floppy and harder to work with on a flat surface.
Drills (Diamonds)
Drills are the small resin beads you place on the canvas. They are usually sold in small resealable bags and labeled with a DMC code — a standardized color numbering system used across the craft industry. A kit should include slightly more drills than you need for each color. If a bag seems very light, count a sample and estimate whether you have enough before starting that section.
The Applicator Pen
This is the stylus you use to pick up and place drills. It has a hollow tip that grips a drill via suction when you press it lightly into wax. Single-tip pens are standard in most kits, but multi-tip pens (which place 3, 6, or 9 drills at once) can significantly speed up large sections of solid color.
Wax or Gel
The small pink or white pad of wax included in kits acts as a pickup medium. You press the applicator tip into the wax before picking up a drill. The light coat of wax creates just enough grip. Replace the wax with a fresh pad when it becomes dirty or loses tackiness.
The Tray
The grooved plastic tray lets you pour out a small quantity of drills, then tilt the tray so they self-orient facet-side up — ready to pick up. This little detail makes the process much faster than picking from a flat surface.

How to Read a Diamond Painting Canvas
The canvas looks overwhelming at first, but the system is straightforward once you understand the basics. Each cell in the grid is printed with a symbol — a circle, square, triangle, asterisk, or one of dozens of other shapes — that corresponds to one DMC color. Your kit will include a legend (sometimes called a color key) that maps each symbol to its DMC number and usually to the color bag it corresponds to.
Reading the Legend
Before you start placing drills, take a few minutes to sort your drill bags and match each one to the legend. Many crafters use small labeled containers or the resealable bags themselves, arranging them by DMC number or color family. Having drills organized before you start saves considerable frustration mid-project.
The Grid Coordinates
Most canvases include faint grid lines or numbered borders that divide the design into sections. These help you find your place if you need to take a break or verify a symbol that is unclear. Printed symbols can sometimes look faded or ambiguous — in those cases, zoom in on a digital copy of the pattern if one is available, or match the surrounding colors contextually.
Tip: Always peel back only a small section of the protective film at a time — roughly the area you plan to complete in a single session. Exposed adhesive attracts dust and pet hair, which can prevent drills from sticking properly.
Round vs Square Drills: Which Should You Choose?
This is the most common question from beginners, and both types have genuine advantages.
Round Drills
Round drills (2.8mm diameter) are the easiest to work with. They are more forgiving of slight misplacement because a circle does not have corners to misalign. They also snap into position more naturally due to their shape. The gap between round drills creates a visible grid pattern in the finished piece, which some people love and others find distracting. Round drills are the standard choice for beginners.
Square Drills
Square drills (2.5mm) fit flush against each other with no gaps, producing a mosaic-like finish that looks more complete and polished. The snap sound when a square drill clicks into place is, for many crafters, deeply satisfying. However, square drills are less forgiving — misaligned drills create noticeable gaps — and they require more careful placement. Most experienced crafters prefer square drills for large projects and display pieces.
Basic Placement Technique
Once your workspace is set up — canvas flat on a table, drills sorted, good lighting — the actual technique is simple. Here is how to develop good habits from the start.
Work in Sections
Start in one corner — most crafters prefer the top left — and work methodically across or down. Completing one color across an entire section before moving to the next reduces how often you need to switch drill bags and minimizes the chance of placing the wrong color.
The Row Method
For large areas of solid color, use a multi-tip applicator and place drills in rows. Pour out drills into the tray, tilt to orient them facet-up, then pick up 3 or 6 at a time and press them down in a line. This is significantly faster than placing one at a time and keeps rows aligned more consistently.
Pressing Drills Down
After placing drills in a section, press them down gently but firmly with your finger or the flat back of the applicator pen. This ensures full contact with the adhesive. Do not skip this step — drills placed but not pressed can fall off when the canvas is moved.
Checking Your Work
Every 20 minutes or so, hold the canvas at an angle to the light. Loose drills will catch the light differently from well-pressed ones, and you can spot any you missed. It is much easier to fix these now than after the canvas is sealed.
Common Beginner Mistakes to Avoid
Working Under Poor Lighting
Dim lighting makes it very difficult to distinguish similar-looking symbols and to tell apart colors like navy and dark purple or light pink and pale lavender. A daylight LED lamp or a dedicated light pad (placed underneath the canvas) makes an enormous difference. This is probably the single most impactful thing you can do to improve your experience from the start.
Peeling the Whole Protective Film at Once
The adhesive layer on diamond painting canvases loses its grip when exposed to air and dust over time. Peel back only as much film as you can complete in a session. If you accidentally expose a large area, cover it loosely with a piece of parchment paper until you return.
Misreading Symbols
Some symbols look very similar — a filled circle and an outlined circle, or a small cross and a small plus sign. Before starting a new color section, double-check the legend rather than assuming. A few minutes of careful checking can prevent hours of picking out wrongly placed drills.
Skipping the Final Press
Many beginners place drills and consider the section done without pressing them. Drills that are not fully bonded to the adhesive can shift or fall, especially when the canvas is moved or rolled up. Get into the habit of pressing completed sections before moving on.
Finishing and Sealing Your Work
Completing your first canvas is genuinely exciting — but the work is not quite done. A finished piece needs to be sealed and, ideally, framed or mounted.
Rolling the Canvas
Before sealing, place a clean cloth or piece of parchment paper over the canvas and roll over it with a rolling pin or brayer. This applies even pressure across all drills, ensuring they are fully bonded and aligned. It also helps square drills click into tight, gap-free rows.
Sealing
Sealing prevents drills from falling off over time and protects the finished piece from dust. The most popular method is applying a thin, even coat of diamond painting sealer (a diluted PVA or acrylic medium) using a foam brush. Work across the canvas in one direction and allow it to dry completely before applying a second coat. Avoid sealing near an open window — dust particles will settle into the wet sealer and create a cloudy finish.
Framing
Standard frame sizes from craft stores often fit common canvas sizes. Alternatively, many canvas sizes match standard photo frame dimensions. Stretch the finished canvas over a wooden frame (like an artist canvas) for a professional, gallery-ready display. Some crafters have their sealed work mounted on foam board and custom framed.
