Difficulty in a numbered canvas is not about artistic skill. It is about how small the sections are, how many near-identical colors you have to tell apart, and whether the subject punishes a wobbly edge. Understanding those four things lets you look at any design and predict how hard your evenings are going to be.
The four things that make a canvas hard

Section size. The obvious one, and the one that decides most of it. When a section is narrower than the brush, you are painting it in several passes with the tip, and there may be hundreds of those. This is also why the same design is genuinely easier at 16x20 than at 12x16 — the artwork is identical, but every section is physically larger.
Color count and how close the colors are. Twenty-four distinct colors is straightforward. Twenty-four colors of which six are near-identical mid-greens is not, because you spend as long checking which pot you are holding as you do painting. Designs with a lot of foliage, water or sky are usually the ones with the crowded palettes.
Value range. A design that lives mostly in the middle of the scale, with no strong lights or darks to anchor it, is hard to judge as you go. You cannot tell whether it is working until a great deal of it is done.
The subject. Some things forgive an imprecise edge and some do not. Trees, rocks, foliage and clouds are forgiving. Water reflections, animal fur, feathers, faces and anything architectural with straight lines are not, because the eye knows exactly what those are meant to look like.
The demanding designs in our catalog
These are the ones our own customers consistently describe as challenging. That is a recommendation for some people and a warning for others, so here they are with the reason.
Seaside Paradise is the most demanding thing we sell. Palms, beach chairs and a tropical shore at sunset, which means a lot of fine frond work over a sky that is changing color behind it. More of our reviewers flag this one as difficult than any other design.
Mountain Village has architecture in it. A church spire, a stone bridge, rooflines and windows, all of which have to be straight, plus water underneath them that has to hold a reflection. The two hardest categories in one canvas.
Golden Hour looks like it should be simple, and that is the trap. It is a shoreline at dawn with a distant lighthouse, painted almost entirely in close pale golds. Very little contrast to guide you, and the palette is full of near neighbors.
Orchard Puzzle is a dozen songbirds on blossoming branches, and every bird carries fine plumage markings in small sections. It is one of our best-loved designs and one of the slowest.
Bamboo Tiger is fur and face. The stripes are forgiving; the eyes are not, and the whole painting stands or falls on a small area you paint near the end.
Enchanted Woods — despite the name, a snowy log cabin with chickadees — packs a great deal of fine detail into the snow-laden branches. Moonrise Song puts wolves against snow, which is a lot of subtle near-white values. Morning Ride is a bicycle at a beach fence, and bicycles mean thin straight lines. Sweet Petunias looks like an easy floral and hides a great many small overlapping petals.
If you want the challenge, set yourself up properly
- Light is the first thing, not the last. A daylight-temperature lamp positioned so your hand does not shadow the canvas changes what you can see more than any brush will.
- A magnifier is not an admission of anything. The finest sections on a detailed canvas are small enough that plenty of people with perfect vision use one.
- Work in short sessions. Detail work degrades with fatigue quickly, and the section you paint at the end of a three-hour stretch is the one you will be repainting.
- Do the darks first. They give you something to judge everything else against, and mistakes in dark sections are far easier to cover than mistakes in light ones.
- Order the extra paint at the same time as the kit. Detailed designs use more paint on the heavily worked colors, and there is an extra paint set matched to each design.
If you want the opposite
Open landscapes with large sections and a clear range from dark to light are the easy end: cabins, lakes, barns, and single-subject bird designs. Our beginner guide covers how to read a design before buying it, and the whole catalog sits in one collection so you can judge by the artwork rather than the title.
One honest note to finish. A hard canvas is not a better canvas. The reason most people paint these is the hour of quiet in the evening, and a design that has you squinting and frustrated is not delivering that. Choose the difficult one because the picture is the one you want on the wall, not to prove something.
