The sketchbook challenges that work best for me usually have one rule, not 30 different prompts. I might draw the same subject for a week, use one pen for several pages, return to the same place repeatedly, or spend five minutes a day working on one skill.
I have kept sketchbooks for years, and I have gone through plenty of periods where I stopped knowing what to put on the next page. A challenge helps most when it removes a decision rather than adding another obligation.
So instead of treating this as a checklist you have to complete perfectly, choose one of the ideas below, change the rules to fit your schedule, and see where it takes your drawings.
The Simplest Way I Build a Sketchbook Challenge
I usually combine three things:
- One focus: a subject, place, material, or drawing skill
- One constraint: a time limit, tool, size, technique, or rule
- One duration: several pages, three days, one week, or however long still feels interesting
For example:
Draw birds + only use ballpoint pen + fill one page a day for five days.
Or:
Draw the same tree + limit each sketch to five minutes + return three times this week.
That is enough structure to get me started without deciding the contents of every future page before I begin.
Fill Seven Pages With One Subject
This is probably the challenge I would recommend first.
Choose one subject and give it seven pages.
It could be:
- crows
- shoes
- trees
- hands
- chairs
- clouds
- faces
- insects
- cars
- houseplants
I would not decide exactly what every page has to look like.
One page might contain a careful observational drawing. Another could have tiny gestures. Another could be drawn from memory. I might zoom in on details, change materials, exaggerate the shape, or draw several versions on one page.
Repeating the subject removes the question of what to draw while still leaving plenty of room to experiment.
If choosing the subject is the hard part, browse my sketchbook theme ideas instead of trying to make this challenge cover every possible theme.
Use One Tool Until It Stops Feeling Ordinary
Choose one drawing tool and use it for an entire challenge.
For example:
- one ballpoint pen
- one graphite pencil
- charcoal
- colored pencil
- brush pen
- one watercolor brush
At first, the limitation can feel boring. That is partly why I like it.
Once I stop switching materials every time I want a different effect, I start finding more ways to use the tool already in my hand.
With a pencil, I might explore pressure, edge quality, broad side shading, sharp lines, and erasing. With ballpoint, I can work with hatching, scribbles, pale pressure, dense shadows, and broken contours.
The challenge becomes less about finishing drawings and more about finding the range inside one material.
Ban One Habit for a Week
Sometimes I learn more by removing something I rely on.
One of the most useful versions for me is drawing without depending on heavy outlines.
You could temporarily ban:
- outlining every object
- using an eraser
- blending shadows
- drawing from photographs
- using color
- drawing larger than a few inches
- using your dominant hand
The point is not that the banned habit is bad.
I am removing it long enough to notice what I do when it is unavailable.
If you depend heavily on contour, try my guide to outlining in drawing alongside the challenge. For an even stronger disruption, try a few pages of non-dominant hand drawing.
Return to the Same Place Several Times
This turns the challenge into a small record of a place.
Choose somewhere easy to revisit:
- a neighborhood park
- your backyard
- a coffee shop
- the view from your window
- a trail near home
- a street corner
Draw there three, five, or seven times.
The location stays the same, but almost everything else can change. Light moves. People appear and disappear. Plants change. Weather shifts. I notice objects I ignored the first time.
I like this challenge because I stop searching for a spectacular subject and start paying more attention to an ordinary place.
If you naturally start adding notes about weather, plants, animals, or what you observe, this can easily become a form of nature journaling.
Draw the Same Thing From Observation and Memory
First, draw something while looking directly at it.
Then close the sketchbook or move away and draw it again from memory.
I like comparing the two drawings afterward.
The memory version usually reveals what I actually noticed. Certain proportions become exaggerated. Some details disappear entirely. One characteristic may become much stronger than it was in the observational drawing.
You can repeat this with:
- a face
- an animal
- a building
- a plant
- a vehicle
- a landscape
It becomes both a memory exercise and a way to discover which visual information feels important to you.
Give Yourself Five Minutes Per Drawing
A challenge does not have to require an hour every day.
For this one, I set a timer for five minutes and stop when it rings.
I can make one drawing a day or fill a page with several sketches in one sitting.
The time limit forces me to decide what matters.
I am much less likely to spend four minutes rendering one eye when I know the entire drawing only gets five.
If five minutes still feels like too much, use two. If you consistently want more time, increase it.
The challenge should create momentum, not prove that you have discipline.
Choose One Skill and Make Ten Studies
This version has a clearer learning goal.
Choose something you actually want to improve:
- hands
- heads
- movement
- perspective
- shading
- line weight
- animal anatomy
- fabric folds
Then make ten small studies rather than one ambitious finished drawing.
I like this because every drawing can answer a slightly different question.
If I were practicing heads, for example, one study might focus on proportion, another on profile, another on shadow, and another on the way the neck connects to the skull.
This is closer to deliberate practice than a traditional prompt challenge. My guide to how to practice sketching goes further into that approach.
Fill a Page Without Drawing an Object
For this challenge, I do not draw a recognizable subject at all.
I fill the page with marks.
They might be:
- short scratches
- overlapping loops
- dots
- heavy blocks
- parallel lines
- broken strokes
- soft graphite patches
- repeated angular marks
I might vary pressure, spacing, speed, direction, or scale.
This is useful when I feel as though every drawing has to depict something important.
A page of marks lets me pay attention to the physical act of drawing again. My mark-making guide explores this in more depth.
Make a Visual Diary for Seven Days
Instead of choosing a drawing subject ahead of time, make one small sketch of something that happened each day.
It does not need to be important.
You might draw:
- what you ate
- someone you saw
- the weather
- an object you bought
- a plant on a walk
- the view from where you sat
- something strange you noticed
I would add a few words when they help preserve the memory.
By the end, the challenge creates a small record of the week rather than seven unrelated exercises.
Redraw an Old Sketchbook Page
Open an older sketchbook and choose something you drew months or years ago.
Draw it again.
I do not try to recreate the old version perfectly. I use the same subject or idea and respond to it with whatever I know now.
Sometimes the technical improvement is obvious. Other times the older drawing has an energy I actually prefer.
Either result is useful.
You can extend this into a larger challenge by choosing five old pages and revisiting one each day.
Combine Two Unrelated Prompts
This is the challenge I use when observational drawing starts feeling predictable.
Choose two unrelated words and force them into one image.
For example:
- jellyfish + alarm clock
- owl + subway
- cactus + astronaut
- fox + library
- storm cloud + teacup
The results do not need to make sense.
The rule forces me to make connections I probably would not have invented if I were staring at a blank page trying to be original.
For a larger pool of starting points, use my random themes to draw or drawing prompts.
Make Every Drawing Fit Inside a Tiny Box
Draw several small rectangles across a sketchbook spread and make every drawing fit inside one.
The tiny size forces me to simplify.
I cannot render every leaf, wrinkle, window, or strand of hair, so I have to think about:
- silhouette
- large value shapes
- proportion
- direction
- composition
This works especially well with landscapes, people, animals, or objects that normally tempt me into too much detail.
Build a Challenge Around One Question
Some of my favorite challenges are not based on subjects at all.
They begin with a question.
For example:
- How many ways can I draw movement?
- How little information do I need to suggest an animal?
- What happens if I never use an outline?
- How can I make a drawing feel quiet?
- What kinds of marks make something feel heavy?
- What changes when I draw entirely from memory?
I can spend several pages answering the same question differently.
That creates more continuity than moving through unrelated prompts simply because they appear next on a list.
Know When You Actually Want a 30-Day Drawing Challenge
There is nothing wrong with doing a traditional daily challenge.
I just would not choose 30 days automatically.
If the purpose is to build a daily habit, then a longer consecutive challenge can make sense. If I only want to experiment with one material or shake off an art block, three days or seven pages may be enough.
If you specifically want a day-by-day format, use my 30-day drawing challenge ideas. I would keep that structured format separate from the flexible sketchbook challenges on this page.
Change the Challenge When It Stops Producing Anything Useful
I do not think finishing an arbitrary rule is automatically more valuable than changing it.
If drawing the same subject for seven days becomes interesting enough that I want to continue for a month, I continue.
If I understand what I wanted to learn after three pages, I may stop early.
If one restriction creates an unexpected direction, I follow it.
The challenge exists to support the sketchbook, not the other way around.
If You Are Stuck, Make the Rule Smaller
When a sketchbook challenge starts feeling like another unfinished project, I reduce it.
Instead of:
Draw every day for a month.
I might use:
Fill three pages with drawings of birds using one pen.
That gives the challenge a clear ending and makes it much easier to start.
If the real problem is simply not knowing what belongs on the page, my sketchbook ideas for beginners and things to draw in your sketchbook are better places to look for subjects.
If the problem is consistency rather than ideas, use my daily sketching routine or sketchbook tips for beginners.
A Good Sketchbook Challenge Should Leave You With Another Idea
I do not judge a sketchbook challenge by whether I completed every planned day.
I care more about what it leaves behind.
Maybe seven drawings of one bird turn into a larger wildlife piece. Maybe one week without outlines changes how I shade form. Maybe repeatedly drawing the same park makes me notice seasonal changes I had ignored. Maybe a strange random prompt gives me a subject I want to develop further.
That is when the challenge has done its job.
It got me past the blank page and gave me something worth drawing next.
