Quick answer: To do diamond painting, lay the adhesive canvas flat, peel back a small section of the protective film, and pour one color of resin drills into the tray. Press the applicator pen into the wax pad, pick up a drill and place it on every printed symbol that matches that color’s code, then move to the next color or section. When the canvas is complete, press the drills down firmly with a roller or heavy book and, if you like, seal and frame it.
Diamond painting sits somewhere between paint-by-numbers and mosaic. Instead of brushing paint onto numbered shapes, you stick hundreds or thousands of tiny faceted resin “diamonds” onto a sticky canvas, one symbol at a time. The result sparkles in a way paint cannot, and the process is calm and repetitive in a good way.
This guide covers how to do diamond painting from unboxing to framing: what each item in the kit does, how to read the legend, step-by-step placement, speed techniques, sealing and the mistakes that cause gaps and crooked rows. If you have not chosen a kit yet, our comparison of the best diamond painting kits on Amazon explains which canvas sizes and drill types suit beginners.
What Is a Diamond Painting Kit?
A diamond painting kit is a complete craft set built around a pre-printed canvas. Each square of the design is marked with a symbol, and each symbol corresponds to a color of resin drill. Most kits include:
| Item | What it does |
|---|---|
| Adhesive canvas | Printed design with symbols under a clear film; the glue holds drills in place |
| Resin drills | The “diamonds,” bagged by color and labeled with a code number |
| Applicator pen | A stylus with a hollow tip that picks up drills |
| Wax or putty | Pressed into the pen tip to make drills stick to it |
| Drill tray | A ridged tray that helps flip drills facet-side up |
| Tweezers (sometimes) | For removing misplaced drills or straightening rows |
Round vs square drills
Round drills are easier to place because they do not need to be aligned edge to edge. They leave small gaps between drills, which some people like for a softer sparkle. Square drills fill the grid completely and create a crisp, mosaic-like finish, but each one must be straightened against its neighbors. Beginners usually find round drills more forgiving.
Full vs partial drill
Full drill kits cover the whole canvas. Partial drill kits leave some areas printed so the image shows through. Partial drill projects are faster and work well as a first try.
What You Need Beyond the Kit
- A clean, flat work surface larger than the canvas.
- Good light. A daylight-balanced lamp makes symbols far easier to read.
- A few small containers or a multi-section bead organizer for storing opened drill colors.
- Parchment or wax paper to cover areas you are not working on.
- Heavy books or a rolling pin for flattening.
- Optional: a light pad placed under the canvas to make symbols glow through.
How to Do Diamond Painting Step by Step
1. Flatten the canvas
Canvases usually ship rolled, which makes them curl. Unroll the canvas with the printed side facing up, then roll it gently the opposite direction for a minute. Lay it flat and place heavy books on the corners for a few hours, or overnight if it keeps curling. Do not peel the film yet.
2. Check the drills against the legend
Along the canvas edge you will find the legend: a list of symbols, each matched to a code number (often a DMC-style code) and sometimes a color swatch. Lay out the drill bags and make sure each code in the legend has a matching bag. If a color is missing, contact the seller before you start.
3. Peel back a small section
Start in a corner or along the bottom edge. Peel back only a few inches of the protective film, enough to work comfortably. Exposing the whole canvas lets dust, pet hair and lint settle on the glue, which weakens adhesion.
4. Load the tray
Pour a small amount of one color into the tray. Gently shake it side to side; the ridges help drills flip so the flat side faces down and the faceted side faces up.
5. Prepare the pen
Peel back the wax cover and press the pen tip into the wax a few times until the hollow end is filled. The wax creates just enough stickiness to lift a drill.
6. Place the drills
Touch the pen to the faceted top of a drill; it will stick. Place it on a matching symbol and press lightly. Repeat for every matching symbol within your exposed area. Refresh the wax when drills stop picking up reliably, usually every few dozen placements.
7. Move color by color or block by block
Either finish all of one color in the exposed area before switching, or work in small square blocks completing every color. See the method comparison below.
8. Cover and continue
Lay the film back over finished sections, or cover them with parchment paper, then peel the next section. Working with your hands over covered areas keeps the glue clean.
9. Press everything down
When the canvas is finished, place the film or parchment over the whole surface and roll firmly with a rolling pin, or press with heavy books. This seats every drill into the adhesive.
Placement Methods: Which Is Fastest?
| Method | How it works | Good for |
|---|---|---|
| Color by color | Place every symbol of one color in the open area, then switch | Fewer pen and tray changes; large single-color zones |
| Block by block | Fill one small square completely before moving on | Straight rows; satisfying visible progress |
| Checkerboard | Place every other drill in a color area, then fill the gaps | Square drills; keeps rows aligned |
| Rolling | Use a multi-tip pen head to place several drills in a line | Large areas of one color |
Many crafters combine methods: rolling for big backgrounds, color by color for mid-size areas, and single placement for detailed faces or edges.
How to Use a Diamond Painting Kit Well: Tips for Clean Results
Keep rows straight with square drills
After placing a row or block, run a straight edge, such as a ruler or the flat side of tweezers, along the row and nudge drills into line. Fix alignment early; the glue firms up over time.
Do not touch the glue
Fingertip oils reduce stickiness. If an area does lose its grip, a very thin layer of clear-drying craft glue can help, but test on a small spot first.
Use the right pen tip
Most pens accept multiple heads. A single tip is best for detail; multi-placer heads speed up large single-color areas.
Manage the extras
Kits usually include more drills than needed. Store leftovers by code in labeled containers; they are useful if a drill pops off later.
Take breaks for your eyes and wrists
Diamond painting is repetitive. Look away from the canvas every so often and change your hand position to avoid strain during long sessions.
Diamond Painting Kit for Beginners: Choosing Your First Project
The biggest beginner mistake is starting too big. A small canvas finished in a few sessions teaches the whole process and builds confidence.
- Size: Around 8 x 12 inches to 12 x 16 inches is a comfortable first project.
- Drill type: Round drills are easier to place.
- Color count: Fewer colors (roughly 20 to 30) means less sorting and fewer similar shades.
- Design: Bold shapes and clear contrast are easier than soft gradients and portraits.
- Clear symbols: Look for kits known for crisp printing and an easy-to-read legend.
Tips to find diamond painting kits worth buying
Read recent buyer photos, not just product images, to check print clarity and color accuracy. Look for kits that list exact canvas size, drill shape, color count and whether drills are standard or AB (iridescent).

Sealing and Framing a Finished Diamond Painting
Should you seal it?
Sealing is optional. A well-pressed canvas in a frame behind glass usually holds up fine. Sealing helps if the piece will be handled, hung without glass, or kept somewhere humid. Crafters use brush-on decoupage medium or a clear spray sealer made for crafts. Some sealers can dull the sparkle slightly, so test on a corner or a practice strip of leftover drills first.
Framing options
- Standard picture frame: Trim the blank canvas margins, then frame with or without glass.
- Stretched canvas: Mount the finished canvas over a stretcher frame or foam board for a gallery-wrap look.
- Magnetic or snap frames: Designed for diamond paintings and easy to swap.
Troubleshooting Common Diamond Painting Problems
The canvas will not stay flat
Reverse-roll it, then flatten under books for longer. Some crafters tape the corners to the table while working.
Drills keep popping off
The glue may be contaminated with dust or skin oil, or the drills were not pressed in firmly. Roll the area again. For persistent spots, apply a tiny amount of clear glue.
I placed the wrong color
Lift the drill with tweezers or the pen and replace it. Do this as soon as you spot it, before the adhesive sets.
Symbols are hard to read
Improve lighting, use a magnifier, or place a light pad underneath. Keep the film on until you are ready, since exposed glue attracts lint that obscures symbols.
I ran out of a color
Many sellers send replacements if you contact them. Otherwise, matching code numbers can often be bought separately.
Organizing Drills: A Setup That Saves Hours
On a canvas with 40 or more colors, sorting drills can take longer than placing them if you do not have a system. A simple setup keeps things moving.
- Label as you open. Transfer each color to a small container or organizer slot and copy the code number onto the lid right away. Bags often get mixed up once opened.
- Arrange by legend order. Keep containers in the same order as the legend so you can find a code at a glance.
- Mark finished colors. Many crafters tick off codes on the legend or move finished containers to a separate area.
- Group similar shades. Some kits include several near-identical colors. Keep them apart in your workspace so you do not grab the wrong one.
- Use one tray per color for busy areas. Extra trays let you switch colors without pouring drills back.
Spills happen
Drills scatter easily. Work over a tray or a rimmed surface, and keep a separate “mystery” container for drills you find on the floor. Compare them against labeled colors later in good light, or keep them for filling odd gaps in backgrounds.
What Is Diamond Art Painting Good For?
Beyond wall art, diamond painting kits come as coasters, keychains, greeting cards, notebooks and ornaments. Small items make good first projects and gifts. Larger canvases become long-term relaxing projects that can be worked on in short sessions.
FAQs
How long does a diamond painting take?
It depends on size, drill shape and color count. A small partial drill kit may take a few hours, while a large full drill canvas can take weeks of casual sessions.
Do you have to seal a diamond painting?
No. Sealing is optional and mainly useful for pieces that will be handled or displayed without glass. Test any sealer on a small area first.
What does the code on each drill bag mean?
The code identifies the color and matches a symbol in the canvas legend. Many kits use DMC-style color numbers.
Is diamond painting hard for beginners?
No. The process is simple, and a small round-drill kit with clear symbols is very approachable. The main skill is patience.
Why are my square drills crooked?
Square drills need alignment. Straighten rows with a ruler or tweezers as you go, and use the checkerboard method so each drill has neighbors to line up against.
Can I reuse the wax?
Yes. Keep the wax pad covered between sessions so it does not collect dust. Replacement wax and putty are widely available if it dries out.
Final Thoughts
Doing diamond painting well comes down to a flat canvas, small exposed sections, good light and steady habits with the pen and wax. Start with a modest round-drill project, press everything down firmly at the end, and frame it to protect the work.
