Epoxy resin starfish are a fun and beautiful project to make. They can be a decoration on their own or be added to a larger epoxy resin project. I just love the way they look and being from the coast, I have them all over my house.
Follow our easy tutorial to make this stunning project.
Project time: 24 hours
Difficulty level: Easy – perfect for beginners
What you’ll need:
- Epoxy Resin
We love Apex Resin. You can use code RESINFORBEGINNERS to get 15% off.
We used their 1:1 high gloss resin for this project. It cures perfectly in 24 hours (or less if using a curing machine) and has the best shine to add to this mould. - Resin Starfish Mould

Use disposable plastic or reusable silicone mixing cups for mixing the resin. We like to save yogurt pots too but make sure they’re washed really well. - Stir Sticks
Silicone stirrers are best for mixing resin as they create the least amount of bubbles but are also easy to clean. You can also use plastic or wooden lollipop sticks. - Heat Gun, lighter or isopropyl spray
Heat guns are a quick way to remove air bubbles from the resin. Make sure it is a crafting heat gun you buy rather than a DIY heat gun as they can be too powerful and will melt moulds and damage your resin. Isopropyl alcohol spray is a great alternative that is less likely to cause damage to any mould and can also be used to help clean your equipment. - Protective equipment
Wear gloves, safety goggles, and work in a well-ventilated area not around children or pets. You may choose to use a respirator mask if your chosen resin is not free from VOC’s or toxins. Read more about resin safety here. - Measuring Scale / Measuring Cups
Resin will either need to be measured in volume or weight. Always check your instructions as this will vary between brands and sometimes even between resin type.

Step by step guide:
- Prepare Your Workspace:
Cover your work surface with plastic. Clingfilm works well for this. Make sure the area you are working in is well-ventilated. - Safety First:
Put on gloves and safety goggles. Epoxy resin can be harmful to your skin and eyes. A respirator mask is also recommended for resins that contain toxins or VOC’s. If you’re unsure, check the guidelines for the type of resin you are using. - Measure and Mix:
TIP: Fill your mould with water then pour it into a measuring cup to see what volume of resin you need. Remember to dry your mould fully before adding your resin. We use sharpies to write on the outside of each mould for next time.
Measure the epoxy resin and hardener according to the instructions on the packaging. Typically, most beginner crafting resins will be a 1:1 ratio and measured by volume.
Use separate cups for the part A and part B then combine them in a third cup.
Stir the mixture slowly for about 2-3 minutes. Making sure you scrape the sides and bottom of the cup. You want the mixture to be clear and streak free. If it is not, then it is unlikely to set properly or may be cloudy when it sets. Stirring slowly will reduce the number of bubbles in your mixture. - Pour Resin into Moulds:
Pour the resin mixture into your mould. - Remove Air Bubbles:
Tap the sides gently to help the resin fill each gap.
You can also use a heat gun or heat torch to carefully pass the flame over the resins’ surface. This will help eliminate air bubbles. Be cautious not to overheat the resin or get too close to it or you’ll damage the resin and mould. - Let It Cure :
Allow the resin to cure. - Demould:
Once the resin is fully cured, carefully remove your frog from the mould. - Enjoy Your Starfish
And just like that you’re done!
TOP TIPS:
Remember to follow safety precautions when working with epoxy resin and be patient during the curing process. Experiment with different colours and designs to create unique starfish or create a collection to add to a bigger project.
