"I'd been wishing for quite a while to "upgrade" from Tiffany-style stained glass pieces (very nice though) to the more classical and immortal work of real painted glass, with kiln, colouring, "grisailles" and all the rest.

But I didn't know how to start, what materials and tools to use, or how to go about learning.

This opportunity is now at hand with this very professional course, where one can learn the trade, step-by-step, with these two wonderful masters who not only know it well but can also teach it artfully.

No worries if you're away when a new module is published: your videos will be waiting for you whenever you log on.

You can watch / re-watch the videos any time you want.

This means you can use Illuminate! in these two ways:

  1. Week-by-week as the course progresses, and also
  2. You can return to particular modules whenever you want to revise a specific technique.

"You have beautifully demonstrated a very complex and delicate process which ends in lovely results (hopefully). Like the pieces of a puzzle, the separate steps are all connected. This course really helped me to see how important each one is.

Wonderfully informative: thank you!" (Babs T.)

"What level will I reach by the end of this course?"

This is the glass you'll paint and highlight in module #8:

Illuminate: an online foundation course for the key techniques of kiln-fired stained glass painting

This is where you'll get to when you take this course, Illuminate!

N.B. We start at the beginning.
This is a foundation course.
It is for you if you're new or fairly new to glass painting,
you want a step-by-step refresher course

"How do you teach this course?"

Sometimes we use words and photos e.g. where we summarise a process or a recipe.

Most points we demonstrate with videos.

Lots of videos.

With spoken commentary so you know what's important.

And the same thing seen from different heights and angles so it's like you're with us in our studio.

“Are these videos like I can watch on YouTube?"

No, because we use 3 cameras.

One left, one right, and one in front / above.

3 cameras: that's how we draw your attention to what you need to see.

So no, these videos are nothing like you watch on YouTube.

I love the in-depth videos.

After 45 years I have learned more from these two online courses than in the last 20. Your questioning attitude and dedication to the craft are a true inspiration. Many thanks. (Tom N.)

"Can I download the videos and watch them off-line?"


"How long do I have access to this course?"

For as long as the internet exists.

"What tools, paints and materials do I need?"

You'll find a list inside the course.

You don't need much - e.g. paint, badger blender, tracing brush, painting bridge etc. Nothing strange or difficult to find.

"Why are you publishing the modules week by week? Why not all at once?"

This is because we're giving you a lot of training here. We want you to have time to absorb new information before we send you more.

"What happens when you add new videos and lessons?"

Say you ask a question and we make a video to answer it: we'll post this new video inside the course.

When this happens, you'll never pay extra for all the new material we'll add to this course.

"Do I need to practise?"


Each week we demonstrate two essential exercises: you will need to practise these.

That's the minimum.

We also give you extra designs for anyone who wants more.

"I am a novice to this art form, and I'm happy I decided to buy the Illuminate course, because starting out with basics and lots of practice is the best way to learn and hone your skills. Before Illuminate!, I took "How to mix a perfect lump of paint " and found it invaluable: I wanted more! Williams & Byrne are thorough and positive. And they have the skill to present and instruct even the newcomer to continue to get better with practice and perseverance" (Jill M.)

"How much does this training this cost?"

The price is $67 for all 8 modules:

This is a complete, step-by-step foundation course.

Most modules contain at least 10 videos.

The whole course is packed with designs for you to download and work on by yourself.

Plus, when you have a question, just email us and we'll reply with help.

That's the point - we'll work together.

Please note: enrolment is only open between May 16th and June 5th.

"Why do you close enrolment on June 5th?"

Because we'll focus on this term's students and give them our full attention.

"How much does it cost to train with you in person in your studio?"

Inside Illuminate!, we teach you everything you'd learn with us if you came and spent 2 days in our studio:

  1. Your travel costs: $200 - $750.
  2. Two days' tuition in the studio: $500.
  3. Three night's accommodation and meals: $200 - $300.

The costs mount up:

Anything from $900 to $1,550 or more.

At just US $67, Illuminate! is great value.

It's also convenient.

You can watch it when you want.

You can watch it again and again.

And you can fit it in with your own schedule.


  1. Watch the videos as often as you like and download the designs whenever you want.
  2. Get full, quick email support whenever you have questions.
  3. Buy with peace of mind - in fact, let's talk about that right now:

"What happens if I change my mind?"

You have a 60-day money-back guarantee.

You can use the course for 60 days and make sure it's right for you.

If you want your money back, just email us within 60 days.
