Jesmonite Terrazzo Casting Class: Coasters and Trinket

Learn how to make your own Jesmonite homewares at this unique Sydney workshop



2 hours Location Drummoyne Class size 1 to 10 guests   $110

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.

Our teacher Julie was lovely and explained everything in a good amount of detail so we were able to create some beautiful and unique pieces. The location was easy to find and well laid out for the class.
  • 5/5 from Alyssa Verrender, attended Apr 2025: The instructor was so lovely and friendly, and we came away with great new pieces that we love. We had a great time, and would definitely recommend!
  • 5/5 from Cathy Ma, attended Feb 2025: Such a good time for me and my family! We got to make 3 items each, but I didn't expect us to also be able to make keychains and other little things with leftover jesmonite! I didn't know that making a flower vase would also mean bringing home a couple of dried flowers too it was so much fun and so cute! Great value for money and the teacher is clearly passionate about it, she gave us great food recommendations in the area as well :) 10/10 would recommend, can't wait to go back to try resin as well!
  • 5/5 from Stephanie Tsionis, attended Feb 2025: I really enjoyed the jesmonite class I attended earlier this week. I learnt a lot of things and all my questions were answered. Our teacher was very sweet and patient with us and we got to take home all the stuff we made.
  • 5/5 from Isabella Fraser, attended Dec 2024: The teacher was lovely and we really liked the venue. Great session and I loved walking away with these!
  • 5/5 from Domenica Tindiglia, attended Oct 2024: Julie was great very patient gave great tips made it enjoyable she has a great sense of humour, I would recommend anyone to do this
  • 5/5 from Dania Diab, attended Jul 2024: The Jesmonite casting class was amazing! The trainer was so lovely and polite and helpful we came out with more casting than expected, great bonding experience and relaxing. It is a great way to use your creativity!
  • 5/5 from Amruthaa S, attended Jun 2024: This is the first art workshop that we are attending as a family and we enjoyed it immensely. Julie is such a warm & friendly teacher and she made sure we felt comfortable right from the start. She clearly explained the method and guided us through the whole process giving us our space at the same time. We would treasure the coasters, trinket tray, vases and the plant propogater for the years to come. We will surely attend more workshops during our next visit Thank you Julie for giving us an evening to remember!
  • 5/5 from Dawn Strauss, attended May 2024: Our teacher, Julie, was extremely professional and helpful in all ways. Very happy with the finished product. Julie was very generous with her time and her knowledge. We are doing more classes because of the way that this one was presented. Materials were all provided, venue was very clean and well set up for the class.
  • 5/5 from Kate Efrat, attended Apr 2024: We loved the course. The teacher was lovely, so helpful and kind. Was so enjoyable.
  • 5/5 from Isabel Garcia, attended Feb 2024: The class was excellent. Very friendly environment. More information about parking need to be added. Thanks
  • 5/5 from Pauline Kanhalikham, attended Feb 2024: Our team was given an opportunity to go out and do something 'fun'. We all agreed it should be something creative and if we were to make something, it had to be something we would want to keep or nice to give as a present. Making Jesmonite items satisfied this brief. There were many different items to make, and we could be as creative as we wanted. Julie was a fantastic instructor, friendly, helpful and very welcoming. We loved the venue, it was bright, spacious and the atmosphere just right. Highly recommend this activity.
  • 5/5 from Jennifer Dordevic, attended Jan 2024: Great class. We had a private class and our teacher was incredibly helpful and inspiring. We had such a great time creating beautiful pieces and learning all about Jesmonite and ecoresins. Highly recommended
  • 3/5 from Lara Baumgartner, attended Sep 2023: 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.
  • 5/5 from Ritoo Jurani, attended Jul 2023: Amazing workshop. It was a great learning experience plus it was fun. Thanks to Julie.
  • 5/5 from Renae McNamara, attended Jun 2023: Lots of different options with products and colours and styles to try, and all finished items were packed up beautifully to take home. Highly recommend.
  • 5/5 from Nicole Tomeo, attended Jun 2023: I had a fun experience learning how to make jesmonite trays and trinkets. The teacher was very helpful and was a very fun environment. Will definitely do another class again :)
  • 5/5 from Candace Watts, attended May 2023: So much fun, great team bonding and chat. Creative with amazing pieces to take home.
  • 5/5 from Leanne Gane, attended Mar 2023: 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.
  • 5/5 from Jess McEwan, attended Mar 2023: 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.
  • 5/5 from Amy Yongsiri, attended Feb 2023: 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!
  • 5/5 from Xanthe Warren, attended Feb 2023: What a fantastic course My friend and I had SO much fun! The process is engaging, possibly reproducible at home, the final cast objects were functional, usable and beautiful! Julie is a relaxed, knowledgable and warm teacher. I will be recommending this course to everyone! :)
  • 5/5 from Sarah Wang, attended Nov 2022: 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 :)
  • 5/5 from Angela Perdon, attended Sep 2022: 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.
  • 5/5 from Karl Berge-Venter, attended Sep 2022: Thanks xx xx x x xx xx x x xx x xx x xx x
  • 5/5 from Bronwyn Sheldon, attended Jun 2022: I really enjoyed the class. It was an easy going class. The teachers were well prepared with the materials, and explained what to do very clealy
  • 4/5 from Alyssa Gratil, attended Jun 2022: Had lots of fun learning how to make jesmonite terrazzo coasters / trinkets. I booked a private class with friends to celebrate my birthday. Julie was very helpful and patient with us. Highly recommend this class!
  • 5/5 from Sarah El, attended 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
  • 5/5 from Helen, attended May 2022: 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.
  • 4/5 from Emma Gaulton, attended 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.
  • 5/5 from Naomi McKeown, attended Apr 2022: 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!
  • 5/5 from Hadiya Osta, attended Apr 2022: Such a fun, enjoyable and creative workshop and I really enjoyed every minute of it!
