The Easiest Way To Make A Resin Diorama


Who says ornaments should only be for the holidays? Here’s how you can make a resin diorama that looks like a bubble aquarium ornament.  Plus, it looks great year-round.

Step 1:  Mix resin

Mix your resin, making sure to protect your hands with gloves. After the resin is thoroughly mixed, split it into multiple containers. You’ll need colors for the water and the fish. I mixed several shades of blue for the water, plus one green and one white.

Step 2:  Add to the ornament

After mixing the colors, pour several layers of each color into the ornament. I try to use only a bit of white as an accent color. Once all the resin is in the ornament, you can use a pipette or craft stick to move the resin around a bit to create a more realistic effect of the water for your diorama.

Step 3:  Let cure

Once you have adequately swirled your resin colors around in the ornament, use a heat gun to eliminate any bubbles. Be very careful when using the heat gun and keep it constantly moving; do not leave it in any one spot. If you overheat the ornament, it can melt. Once done, set it aside to cure. I put the ornament in a plastic cup to keep it from tipping over, then covered it with foil to prevent dust and other debris from getting into the resin.

Step 4:  Make the fish

You can make your fish in several different ways:
1. Mix some colored resin to get a unique-looking fish.
2. Use Jacquard Pearl Ex powders to create an incandescent effect.
3. Cast with clear resin and paint it with acrylic paint.

I prefer the last method. However, if you want to paint your fish by hand, use a primer spray on the cured resin piece to get the paint to stick better. I also prefer pearlescent resin colors since they look a little more like scales. You can also mix some of these techniques. For example, you can get a base color using Pearl Ex powders, then add some accents and details using acrylic paint.

Give the water and fish 24 hours to cure (or however long your resin instructs). If you’re adding any details to the fish, ensure they are completely dry before the next step.

By the way, this is why the Resin Obsession super clear resin is great for this diorama project.  Look how clear these resin fish are!

Step 5:  Make the resin diorama

Here’s the point when your resin diorama starts to come alive. Position your fish in the ornament. I glue mine in place with E6000 to make sure nothing happens while the next layer of resin is curing. Once the glue is dry, you can add accessories to the ornament. I like this ornament’s look of dried moss since it creates a little more depth to the project. You may want to use a little glue to secure your accessories when adding them to the piece (though I wouldn’t recommend this for the dried moss, as it doesn’t work well).

Step 6:  Add a new resin layer

Once the glue is dry, mix a new batch of clear resin. Add this layer of resin directly to the parts of the piece showing the blue background and on top of the fish. Try to avoid adding it to the visible parts of the shells just because it affects the look of the shells. If you use dried moss, don’t the resin on top, as it makes the moss look more clumped together. You can use this additional resin to better seal your accessories to the diorama. You may also want to add some bubbles from the fish; you can use pearl beads, stickers, etc., to do that.

Once you’ve added this final layer of resin, put your piece aside to cure. Again, use a cup to ensure the piece stays level.  Cover the top with foil.

Step 7:  Finish

Once the final layer of resin is dry, you can decide how you want to show off your piece. You can make it look like it’s in its little bubble by putting the other half of the ornament on, or you can leave it off your resin diorama.

Imagine making something with resin with people saying, ‘Wow, that is amazing!’

It may not feel like you can get there, but I promise you can! It’s why I wrote the book Resin Fundamentals.  It contains the vital elements artists and crafters need to know to create with resin every time successfully. So get your copy today and read it in a couple of hours.
