What is the Planters with an Attached Drip Tray printable guide?
It is the planter on paper: why the drainage holes go through the wall and never the bottom, the half inch step and how to check it with a needle tool, three ways to build one, a numbers table for a four, six and eight inch planter, how to dry the fast half and the slow half together, and the four ways glaze ruins one. Built to be printed, written in and kept on the bench for the week the drying takes.
Prefer to read it online first? The “Planters with an Attached Drip Tray” lesson is free, and always will be.

Nobody makes a bad planter. They make a bad decision about the water
Throwing the pot is the part everybody is confident about. The tray is the part nobody thinks about until the plant is in it and there is a puddle under the pot.
A saucer you can lift has one job, and you do it without noticing: you pour it out. Attach the saucer and that job is gone, so the water has to sit somewhere lower than the soil, where you can see it and reach it with a sponge. Whether it does is settled by half an inch of clay, measured in the first few minutes of the throw.
That measurement, the drains that go through the wall, and the week of drying that keeps the inside corner from cracking are the whole difference between a planter and a very heavy ornament. Everything else is ordinary throwing.
Real pages, for a bench with a needle tool on it
These are actual pages from the guide, shown here with the sample watermark.

Before you beginSix boxes on one page: what you will learn, what to have on the bench, what is worth knowing, the common pitfalls, what success looks like and how to practice. Read it before you throw and again before you glaze. 
The cross-sectionThe whole planter cut in half, with six numbered parts and the key beside the drawing rather than underneath it. It says plainly that it is a sketch, and the real proportions are in the numbers table. 
Nine ways it goes wrongFind the symptom, read the cause. Nearly every one was decided at the wheel, days before it showed, which is the annoying part and also the useful part. 
Every planter, and the step you setA log to write in: the route, the size, the step you set, how many days it took to dry and what actually happened. Two rows in and the second planter starts from a number instead of a memory.
You will be looking at it with a wet hand
A planter with a tray gets decided in short bursts at the wheel, with days of waiting in between. Paper suits both.
It holds still
A page stays exactly where you left it while you rib a floor with both hands. It does not time out, and it does not need slip wiped off the screen.
A week in the middle
The drying takes about a week and the corner is the thing to watch. Nobody rewatches a sixteen minute video to remember what to do with the plastic. They come back to a list.
A number to write down
The step is one measurement you set with a needle tool. The guide has a page to put it on, next to how long the planter took to dry.
It pins up
The checklist belongs beside the wheel and the drying rules belong above the shelf, because that is where the question actually gets asked.
Rebuilt for paper, not printed from a web page
Every guide in the series is set from scratch for print. Here is what that meant for this one.
The numbers, run again
The water each planter size holds was recomputed from the tray and planter sizes in the table, and the moat widths follow from the tray diameters. All of it agrees.
A drawing that says what it is
The lesson’s cross-section called itself drawn to scale. Measured, it is a sketch, so the guide says so and points you at the numbers table for the real proportions.
The kiln rule, put back
The glazing list now says what the studio has always said about a wide flat foot: it goes on a glaze catcher or a kiln cookie, every time.
Written for any studio
Our cone numbers, our clay and our glazes are named as ours and dated, so a reader working somewhere else knows which parts are a Clay Hole fact and which are a rule of the craft.
A quiz that explains itself
Six questions, and an answer key that gives the reason behind every answer rather than only the letter.
Codes that keep working
Every link is a short Clay Hole address. If a video moves, we repoint the address and your printed copy still goes to the right place.
The lesson is free. It always will be.
All of the teaching in this guide comes from the free “Planters with an Attached Drip Tray” lesson, and that lesson is not going anywhere.
I have lost count of the planters that come back to the bench with a plant in them and a puddle under them. Nobody made a bad pot.
It is not a throwing problem. It is a plumbing problem, and plumbing gets settled with a measurement, not with skill.
Make a small one first, live with it for a month, and the big one will still be there.

Build a little pottery library

Three lessons that pick up where this one leaves off
Each one is free to read online, and the codes in the guide take you straight there.

Guide 06.11 · free lessonThrowing PlatesThe tray of this planter is a wide flat floor with a pot standing in the middle of it. “A plate is mostly floor, and the floor is the part that cracks” is that guide’s whole subject, and it applies to your tray word for word.

Guide 06.14 · free lessonFolding Rims OverBoth rims on this piece get compressed and neither gets folded. If you want the pot’s rim to be the strongest ring on it, that guide is for bowls and planters, and it is a different answer to the same weak edge.

Guide 08.06 · free lessonHow to Make Kitchen StrainersCutting clean holes in leather hard clay is most of what a strainer is, and every drain in this guide is one. Timing, tools and burrs, worked out properly.

Good to know
How is this different from the free lesson?
Do I need a wheel?
Do I need a bat?
Is this too early for me?
Can I use it for a planter that lives outside?
Do I need a fancy printer?
Does it print in black and white?
Can I print just part of it?
Can I read it on a screen instead?
How does delivery work?
What happens if the guide is updated?
Can I share it?
Set the step first, and the rest is throwing
Get the half inch right, put the drains through the wall, and give the corner a week. Do those three and the rest is ordinary throwing. Get any of them wrong and no amount of skill at the wheel will save it, which is why this one is worth reading before you cut into the mound rather than after.
