What is the Trimming While Throwing printable guide?
It is a printable workbook edition of The Clay Hole University’s free “Trimming While Throwing” lesson. It teaches finishing the foot while the pot is still soft and has never been lifted, walks through four different bottoms and the moves that make each one, and adds the pages that only work on paper: a log with one row per pot, a diagnosis section for the fourteen things that go wrong, a one page card for beside the wheel, a quiz with a full answer key, and a glossary.
Prefer to read it online first? The “Trimming While Throwing” lesson is free, and always will be.

The decision happens in four seconds, with both hands busy
The cut that shapes the bottom of your pot takes about four seconds, and it happens while the wheel is turning and your hands are wet. There is no moment in there to check anything. You either know which bottom you are making and where the tool goes, or you make the one your hand defaults to.
So most people learn one bottom, do it every time, and never find out that the other three were easier. Or they cut in the wrong place once, watch the pot go sideways, and are not quite sure afterwards what they did.
This guide is built to be open on the table while that happens. The route you are making circled in pencil, the setup checked off before the wheel turns, and the log filling in one pot at a time until your hands stop needing the page.
Real pages, built for a wheel that is already turning
These are actual pages from the guide, shown here with the sample watermark. The full guide has none.

Four bottoms, sliced down the middleWhat you are actually making, drawn in section, so the shape you are cutting toward is a picture and not a guess. 
Five checklistsBuilt for a page propped against a bucket. Big rows, short lines, and a box to tick before the wheel turns. 
Fourteen things that go wrongEach symptom, what it really is, what to do about it, and a box to tick for the ones that keep happening to you. 
The pot logOne row for every pot you finish on the wheel. Write the floor down before you pull the first wall, not after.
Why this technique, of all of them, belongs on paper
Everything that decides this cut happens before you pick up the tool, and then it is over in seconds. Paper is the only thing you can check in that window.
It stays open while your hands are covered
Prop it against the splash pan and glance at the route mid throw without wiping off, drying your hands and waking a screen that has already locked.
It remembers what keeps going wrong for you
Tick the rows in the diagnosis section that describe your pots. After a week the pattern is sitting on the page, and the fix is printed next to it.
It turns repetitions into something you can see
One row per pot, the floor written down before the first pull. Somewhere in the first few dozen there is a row where the bevel stopped being a decision, and you will want to find it.
One card lives by the wheel for good
The setup, the bevel and the foot line, and the short version of the other routes, all on a single card. Pull it out of the binder and leave it where you throw.
Built the way a four second habit actually gets learned
Every guide in the series is designed as a workbook first and a document second. For this one, that means:
A learning dashboard before page one
What you will learn, what you need on the tray, the mistakes that get made first, and what a good bottom actually feels like under the tool.
The complete lesson, redesigned for paper
The setup that decides ninety percent of it, all four routes, the moves for each one in order, and the honest section on when to stop and flip the pot over instead.
Five checklists to keep open at the wheel
Built for a page propped against a bucket, with big rows and short lines you can tick without stopping what you are doing.
Videos you can reach from a printed page
Seven videos chosen for what they show rather than who made them, each with a note on why it is worth your time and a code that goes straight to it.
A quiz that teaches instead of grading
Seven questions with an answer key that explains every answer, so a wrong one still teaches you something.
Plain words for the jargon
A sixteen term glossary, from the bevel and the undercut to the S crack, written the way we would explain it to you at the wheel.
The lesson is free. It always will be.
All of the teaching in this guide comes from the free “Trimming While Throwing” lesson at The Clay Hole University. No paywall, no sign-up, no catch.
Finishing a pot on the wheel is about as unglamorous as this craft gets, and it is also the thing that turns a decent pot into a finished one. Nobody should have to pay to find that out, so the lesson stays free, for anybody, anywhere.
The University is free and stays free. The guides are the version rebuilt for paper with an unreasonable amount of care, and buying one keeps the free side going.
Thank you. Genuinely.
