What is the How to Make Kitchen Strainers printable guide?
It is the whole strainer job on paper: which of the four forms you are making, how much bigger than finished to cut the holes, the one drying window they cut cleanly in, and the glazing drill that stops the kiln sealing them shut. The web version’s calculator comes with it as a printed table, so you can work out a hole size with clay on your hands.
Prefer to read it online first? The “How to Make Kitchen Strainers” lesson is free, and always will be.

A mug with a flaw is still a mug
A colander whose holes filled with glaze is not a colander. It is a bowl that holds dirty water, and there is nothing to do with it. That is what makes a strainer different from everything else you have thrown: it is the one piece where one detail decides whether the whole thing works.
Two details, really. How much bigger than finished you cut the holes, which is arithmetic nobody does in their head, and whether you go back and open every single hole twice on glaze day, which is the step everyone means to do and then does once.
Both of those happen with wet hands, under a clock, at the bench. Neither of them happens while you are scrolling.
Real pages, for a wet bench and a glaze bucket
These are actual pages from the guide, shown here with the sample watermark. The full guide has none.

What you will learn, and what goes wrongThe whole guide in one spread before you start: what to have ready, the pitfalls, and what a finished one looks like. 
How big to cut the holesThe lesson’s calculator as a printed table. Finished hole size down the side, how you plan to glaze it across the top, and the cutter to reach for in every cell. 
There is one window, and it is not very wideToo soft, this is the one, too late, repair only. The four stages with what each one does to a hole, so you can tell by feel. 
Work backwards to the hole you wantThe arithmetic as a sheet you fill in: the piece, the finished hole, the shrink rate, the glaze allowance, what to cut and what it came out.
Glaze day gives you about a minute, and both hands are busy
Dip a strainer and every hole floods at once. From that moment you have roughly a minute to open all of them before the glaze sets, with a needle tool in one hand and the pot in the other. That is the worst possible time to be looking for a phone.
It does not go dark
A page sits there showing the drill while you work through fifty holes. No timeout, no scrolling back to find where you were, no wet knuckle on a screen.
You can tick it as you go
Two lists, making day and glazing day, meant to be printed and marked with a pencil. Print them again for the next piece.
The arithmetic is already done
A table of finished hole sizes against the four ways of glazing, with the hole to cut and the nearest standard cutter in every cell. No maths with slip on your fingers.
It survives the studio
Clay dust, glaze splash and a wet bench. A printed page you can replace for nothing beats a phone you have to wipe.
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 calculator, as a table
The lesson’s hole size tool runs in a browser and cannot print. Its formula is worked out here across eight finished sizes and four ways of glazing, with the nearest standard cutter named each time.
The four forms, all at once
Colander, berry bowl, tea strainer and the soap and garlic holders, side by side with the finished hole size each one needs. The web shows you one at a time.
Every fault, not just the one you picked
Six ways a strainer goes wrong, each with what happened, whether this piece can be saved, and what to change next time. On the web they are six buttons.
One drying window, drawn out
Too soft, leather hard, bone dry, after bisque. What each one does to a hole, so you can tell where you are by feel rather than by guessing.
Two working lists and a planning sheet
Making day and glazing day as tick lists, plus a sheet for working a hole size backwards from the size you want and writing down what it came out.
A quiz, an answer key and a glossary
The same questions as the free lesson, with the reasoning behind every answer, and the words this job uses in plain language.
The lesson is free. It always will be.
All of the teaching in this guide comes from the free “How to Make Kitchen Strainers” lesson at The Clay Hole University. No paywall, no sign-up, no trial. This is the same teaching set for paper, so you can take it to the bench.
A mug with a flaw in it is still a mug. You drink out of it, you like it, nobody knows. A colander whose holes filled in is not a colander at all.
People believe the part about cutting them bigger and then skip the part that matters just as much, which is going back and opening every hole twice on glaze day. Glaze films across an opening the way water films across a small ring, and the kiln turns that film into a wall.
Your first one will clog somewhere, and it will clog for a reason you can name. That is more than most first attempts give you, and the second one will be right.

Build a little pottery library
Every printable guide in The Clay Hole University series takes one free lesson and rebuilds it for paper: the teaching in the order you do it, the numbers worked out, the things that go wrong with what to do about each one, workbook pages to fill in, and a quiz with the reasoning behind every answer. This one is number 08.06, in the project guides, and its number never changes.

Guide 07.04 · free lessonHow to Use Slab Molds, Step by StepThe no wheel route, which this guide points at twice: a slab draped into or over a mold, a foot added, holes cut once it stiffens. It is also the lesson on getting a good slab out of a mold, which is the half this guide does not teach, and the studio has 248 molds already cast and free to use with a certification.

Guide 11.01 · free lessonGlaze Brushing Techniques, Coat by CoatBrushing is the route this guide recommends, because it is the one where you decide how much glaze goes near each opening. It does not teach brushing itself: how many coats, how to lay them, how to keep an edge. This is that lesson, and it is the difference between two even coats near the holes and two thick ones.

Guide 12.04 · free lessonScouring, Sanding and Grinding, Stage by StageEvery fault in this guide’s list ends in the same place: a diamond bit, water and patience. This is the lesson on scouring, sanding and grinding stage by stage, wet only, and it covers the rescues this guide can only mention in a line.

Cut them bigger, and open them twice
Two decisions and one drill, and the thing drains instead of holding dirty water. Download it, print the two lists and the planning sheet, and keep them beside you from the first hole to the last glaze pass.
