A month of pages is long enough to see a habit and short enough to remember. Reviewing it is not a marking exercise, and it is not a chance to tear out the ugly studies. It is a way to find what you keep doing, on purpose or by accident, so the next month can change one thing. Without the review, a sketchbook is a diary you never read.

Start with the words

Read the dates and the margin notes before you admire or dislike the drawings. Labelling Sketchbook Pages So They Teach You pays off here. If half the pages have no note, that absence is the first finding. You cannot review a lesson that was never written down. For the pages that do have notes, copy the aims into a short list: ellipses, ten-minute figures, colour of the evening, poster crops.

Count the sittings. A month that felt busy and contains six pages was a month of thinking about drawing. That is useful to know, and it is not a reason to scold yourself. It is a reason to make the book easier to reach.

What repeats

Look for a subject that appears three times or more. Cups, hands, the view from one window, other people's shoes. Repetition is interest. It is also a rut if the drawings are identical in size and in fault. Note the fault beside the subject: cups too small on the page, hands without a palm, windows always centred.

Then look for a fault that appears across different subjects. Everything is pale. Everything is cramped in the middle. Every outdoor page is a contour with no shadow. Thumbnails: Planning a Painting in Small Boxes may be missing, or it may be present and ignored. Write the pattern in one sentence. A review that produces ten criticisms produces none.

What improved, quietly

Find one page from the start of the month and one from the end that attempt the same problem. Compare them without romance. Perhaps the later ellipse is flatter, or the later margin note is clearer, or the later figure has a weight. Name that change. People abandon sketchbooks because they stare only at the pages that still fail.

If you kept colour notes, check whether the studio work you did afterwards used them. A Colour-Note Sketchbook for Outdoor Light is wasted if the notes never leave the book. A review can be as simple as pinning one swatch above the table for the next painting.

One instruction for the next month

Choose a single change, small enough to do on a tired day. Draw larger. Write the aim every time. Include one thumbnail before a painting. Put the book by the kettle. Write the instruction on the next blank page so it survives the mood you are in during the review.

Do not redesign the whole practice. A new sketchbook, a new medium and a new subject, all at once, erase the comparison you just earned. Keep the book. Change the sentence at the top of the page.

Frequently asked questions

How long should a review take? Half an hour is enough for a month of ordinary pages. If you spend the afternoon redrawing the weak ones, you have started a new project and skipped the decision.

Should I throw pages away? No. A weak page with a note is evidence. Tear it out only if the surface is physically spoiled and you have already copied the lesson elsewhere.

What if I skipped weeks? Review what exists, and let the gaps be data. The next instruction might simply be to date a page on more days, not to draw better on the days you already managed.

Steps
