2 hours Class size 1 to 10

label $110 (or 4 payments of $27.50 Afterpay)

Exploding in popularity, Jesmonite or Eco resin has become a go-to material for creating homeware pieces in under 30 minutes. Learn how to create your own terrazzo and swirling techniques for your Coasters and Trinkets from scratch in this fun and exciting workshop in Drummoyne.

Over two hours of casting fun, you'll learn the basics of what Jesmonite is, how to make terrazzo chips, how to create a marbled effect and casting with Jesmonite.

The best part is Jesmonite cures in just 30 minutes so you can bring home what you produced straight after the workshop - the ultimate instant gratification!

Class outline:

  • Design your colour palette
  • Make terrazzo coloured chips
  • Learn how to mix and add pigment to Jesmonite
  • Learn how to cast into a silicone mould
  • Learn various techniques to colour your eco-resin
  • Sand and seal your creations for a polished look

By the end of the workshop, you will take home three items - either two coasters and a trinket or you are welcome to switch an item in our mould collection like a vase. Creativity is your only limitation!

Please note:
Jesmonite is considered safe, does not emit toxic fumes or VOCs, and there are no documented health risks associated with Jesmonite, however, we recommend pregnant women check with their health care professional before working with any chemicals.

A variety of trinket moulds (Oval or shell), and coasters (round/square/hexagon) are available. We also have a huge range of moulds so students have had creative freedom to make a mini vase or jewellery box instead too.

A wide range of pigments, gold leaf/flakes and premade terrazzo will also be available.

We may also test out other brands of eco-resin and pigments with one of the new favourites being an Australian brand of eco-resin called Brambliers.

While we made some nice items in the end, this class was run by someone who was nice but seemed to be filling in and hadn't run the class before (or not in a long time). They asked us whether it was specifically a terrazzo class and how many items we were supposed to be making, which didn't inspire confidence. Things weren't planned out and it felt chaotic to be honest, which isn't what you want from an experience like this. We still had a good time and I liked that we could pick the three items we wanted regardless of size etc, but I expected much more in terms of organisation and direction and wanted it to feel calmer. I don't know if I'd book a class here again.

My friends and I regularly do different craft classes and we all agree Julie was the best. We loved how Julie to the time to explain, encourage us to explore the medium and create some beautiful pieces.
Absolutely would recommend Julie for any future classes.

Three friends and I had a private Terrazzo Jesmonite class with Julie as our instructor and it was fabulous. Julie knowledge of how to use the jesmonite was extensive and her calm and helpful nature just added to the experience. I’m in love with tricker try, coaster and vase. The venue was great and parking on a Sunday very easy. Will definitely do another class with Julie at this location.

Great small class. Learnt lots about the process and the possibilities of casting with Jesmonite. The teacher, Judy was really supportive and generous with her advice, patience and attention to the various questions we all had.
Such a great class! I’d love to do another at the same place!

We had a lot of fun in this class! Julie was really helpful and knowledgeable in giving us an idea of how our designs were going to turn out. She was a really great instructor! All the materials were provided for us. It was cool being able to choose the moulds and make the chips to eventually use in our pieces. Thoroughly enjoyed the class :)

Had a great time learning how to use jesmonite to make these really cool, on-trend objects. All the materials were supplied, even packing supplies to safely transport our items home. I came away with three coasters, a trinket tray, and a vase (an extra thrown-in because my original session had to be rescheduled last minute) and even though it was probably ambitious to attempt so many in the time given, I'm so pleased with the result. You will definitely need some elbow grease to achieve the terrazzo look, but we were given some alternative approaches (like marbling) to achieve a quicker, but equally cool result.

Had a great time at the class the teacher was very helpful and friendly. Venue was good and we were able to find street parking nearby though it was 2 hr so we did have to move car.

Emma Gaulton May 2022


This was well worth the money and was great fun. The teacher was very informative and helpful. The only negative was the sanding which took awhile as your only using sandpaper, if they purchased a small electric hand sander that would speed up the process at the end.

Sarah El May 2022


The teacher wad great! super helpful and knew her stuff. I really enjoyed it. She was generous with us too giving me extra time when my piece didn't set. Shame I broke my piece but its cool. I learnt alot. Thanks

Absolutely loved this! It was a unique craft experience and we both came away with something we will use. Julie was a wonderful teacher and gave us good advice about how we could continue doing what we learnt at home eg suggesting what materials we'd need. I did this with my daughter (age 14) and she enjoyed it as much as I did. Thanks Julie!
