Capture relaxation in a jar with this simple DIY beach terrarium idea using beach finds and a repurposed glass jar.

Why We Love This Project

It’s no secret that we love all things beachy at Sustain My Craft Habit, from sea glass Christmas trees to these hand-lettered DIY driftwood signs, we can’t get enough of beach-inspired crafts. Who doesn’t want to be reminded of the beach all year long? 

Additionally, repurposing glass jars into pretty and useful decor is another crafting obsession. Instead of sending jars to the curb to be recycled, be sure to hold on to them for craft purposes. You never know when inspiration will strike and you’ll want to create something new such as this upcycled large pickle jar centerpiece or this vacation photo jar.

We used some pieces of uniquely shaped driftwood that loosely resembled coral for the center of the jar. Alternatively, you can purchase decorative coral which would also look really amazing inside the jar. 

Craft Supplies You Will Need

We’ve provided a full detailed list in the printable portion of this post of the supplies we’ve used for our jar. However, feel free to use whatever supplies you’d like!

How To Make A Beach Terrarium

Preparing the Supplies:

Wash and dry the mason jar, removing all labels and glue.

For the smaller driftwood pieces, apply a light coat of turquoise paint. We mixed equal parts of Chalky Finish in Everlasting and Vintage Effects Wash in Turquoise to soften the color. Any light turquoise acrylic paint with a matte finish will also work. Put these pieces aside to dry.

Give the tall, “coral-like” pieces of driftwood a coat white paint. We used a Chalky Finish in Everlasting but any white acrylic paint with a matte finish will work as well.

While the paint is still wet, pour some fine glitter over top of the driftwood. Put the pieces aside to dry before placing them in the terrarium.

Once the piece with the flatter surface is dry, use a white paint pen and print the word “breathe” across the front.

Apply a coat of paint to the mason jar lid. Repeat with additional coats as needed to get full coverage.

Assembling the Beach Terrarium:

Pour the sand into the jar. You can use a piece of scrap paper to form a tunnel so the sand doesn’t get everywhere! Tap the jar to help the sand settle and level out at the bottom.

Put a layer of white sea glass into the jar mostly around the perimeter leaving just the center without glass. Use the other end of the paintbrush to help you position the items inside the jar.

Insert the longer “coral-like” pieces of driftwood into the sand in the center of the terrarium. And then position the smaller turquoise driftwood pieces around the “coral”.

Place the seashells and glass beads inside the jar on top of the seaglass.

Lastly, gently insert a strand of white twinkle lights.

Using a preheated glue gun, apply a dab of glue to the bottom of the remaining seashells and press them to the top of the mason jar lid. Next, attach the lid on to the mason jar.

Tie a piece of cotton rope around the neck of the jar.

And there you have it, your beach terrarium is complete!
