Diamond painting sits somewhere between paint-by-numbers and cross-stitch. You get a printed canvas covered in a grid of coded symbols, a set of tiny resin “diamonds” in matching colours, and a pen-like tool. You pick up a diamond, you place it on its square, and slowly a picture appears — one that catches the light in a way a flat print never does.
Make it from your own photo and the appeal changes completely. You are not assembling a stock image of a wolf; you are building a portrait of your own dog, one drill at a time.
This is everything a first-timer needs to decide and to get started.
What is actually in the kit
A custom diamond painting kit contains three things: a printed canvas made from your photo, the resin diamonds, and the tools to apply them.
The canvas is pre-printed with a symbol grid and comes with an adhesive layer under a protective film. You peel back a small section at a time, place your diamonds, and move on. The tools are typically an applicator pen, a small tray for pouring diamonds into, and wax to help the pen pick them up.
Round or square drills?
This is the first real decision, and both options are offered.
- Full round drills are faster and more forgiving. They are easier to pick up with the pen, and because they are circular, being slightly off-angle does not show. There are small gaps between them where the canvas shows through, which gives a slightly softer, more textured finish.
- Full square drills tile edge to edge with no gaps, which produces a crisper, more mosaic-like image and a satisfying click as they line up. They take longer, and a crooked one is visible, so they reward patience.
For a first project, choose round. Finishing something is more encouraging than perfecting something. Choose square when you already know you enjoy it and you want the sharpest possible result — especially for a portrait.
What size should you pick?
Canvas sizes run from 15×15 cm up to 80×80 cm, and this choice matters more than people expect — because size does not just change the finished piece, it changes how much detail is possible.
Each drill is one square of the grid, roughly the size of a grain of rice. A small canvas has relatively few squares to work with, so fine detail — the shape of an eye, a strand of hair, small text — has fewer drills to be described in. A large canvas has far more grid squares and can render subtle detail properly.
Practical guidance:
- 15–30 cm — good for a simple, bold subject: a single pet’s face, a silhouette, a strong close-up. Not the size for a group photo.
- 30–50 cm — the comfortable middle. A single portrait or a couple works well. A realistic weekend-plus project.
- 50–80 cm — for group photos, wedding shots, anything with several faces, or a piece you intend to hang as the focal point of a wall. Expect it to take weeks of evenings, not days.
The rule of thumb: the more faces in your photo, the larger the canvas needs to be. Two people at 30 cm is fine. Six people at 30 cm gives each face perhaps a dozen drills, and nobody will be recognisable.
Which photos work best
Diamond painting rewards a specific kind of image. The medium simplifies — every subtle gradient has to be resolved into a limited set of drill colours on a fixed grid.
Works well: close portraits, pets, a couple, strong contrast between subject and background, good even lighting, a simple or blurred background.
Works less well: wide landscapes with lots of fine detail, busy backgrounds competing with the subject, very dark or backlit photos, and anything where the subject is small in the frame.
As with any photo product, send the original file rather than a screenshot or a version saved from social media — those have been compressed, and the detail that was thrown away cannot come back.
How to actually do it
Set up properly
Work on a flat surface with good light — ideally a lamp positioned to the side, so the symbols on the canvas stay readable. Many people use a cheap A4 light pad under the canvas, which makes the symbols far easier to see. It is not required, but it is the single most common upgrade for a reason.
Roll the canvas out flat and, if it has been shipped rolled, leave it under some books for a few hours first.
Work in small sections
Peel back only a few inches of the protective film at a time. The adhesive picks up dust and loses tack when exposed, so uncovering the whole canvas on day one is the classic beginner mistake.
One colour at a time, or one area at a time
Two schools of thought. Working one colour across the whole canvas is efficient — you pour one bag into the tray and stay with it. Working area by area, using all the colours in that patch, is more satisfying because you see finished sections appear.
Beginners usually enjoy area-by-area more. Start at the bottom so your hand rests on the covered film rather than on finished work.
Technique
Tip a small amount of one colour into the tray and shake gently — the drills settle flat side down. Press the pen tip into the wax, touch the top of a drill, and set it on its square. Press straight down; do not slide it into place. With square drills, a straight edge or the flat side of the tray can be used to nudge a whole row into alignment.
Do not pour out more than you will use in a session, and close the bags — these things travel.
Finishing
When it is done, lay the release film back over the surface and press firmly across the whole canvas — or put a clean cloth over it and go over it with a rolling pin. This seats every drill into the adhesive properly and is what stops them popping off later.
Kits are supplied without a frame, so plan for framing separately if you want to hang it. A standard frame in the canvas size works, and many people leave the glass out so the drills catch the light.
How long does it take?
Genuinely variable, and it depends on drill type and size far more than on skill. A small round-drill canvas is an evening or two. A large square-drill portrait is a project you live with for a while.
That is a feature, not a drawback. Most people who take it up do so because they want something to do with their hands that is absorbing and not on a screen.
Before you order
Every kit is made to order from your photo, and you get a free digital proof within 24 hours. Nothing goes to print until you approve it — so if the crop is wrong, or the photo is not going to hold up at the canvas size you picked, that is the moment it gets sorted out.
Pick your photo, pick round drills for a first go, and pick a canvas big enough for the number of faces in it. That is most of the decision made.
