I love terrazzo. It’s a very elegant material and I would put it all over the house if I could! Since my boyfriend would probably veto the idea, I’m trying to find ways to bring more terrazzo in our life, like with these DIY coasters!
Terrazzo is made from placing small rocks and stones in a soft medium that can dry hard, like concrete or resin, enclosing the stones. The medium is then sanded to reveal cross-sections of the stones. I tried my hand at making a green version, upcycling wood scraps. There were a lot of trials and errors along the way until I found the right medium: air dry clay. It won’t work with homemade clay, like baking soda clay, because of its tendency to crack. Get yourself some air dry clay and make these DIY wood terrazzo coasters!

Step 1: Prep the wood scraps
To begin, gather a few bits of wood scraps and randomly cut them into small pieces. Try to angle the saw to cut different shapes and bring some variation in size as well.
Step 2: Shape the coasters
Next, work the clay to warm it up. This will help you work with it. Break off 4 pieces and shape them into balls. Roll out the balls to get flat circles.
Once you have 4 circles ready, take your small pieces of wood and push them into the clay at random. You’ll notice that the clay gets pushed away when you press the wood in. Make sure you push the clay back into place with your fingers. It’s important that the wood pieces be as enclosed in clay as possible otherwise they might fall off when the clay dries.
When you’re done, find a large jar or bowl to help you trace a circle. Place it on top of the clay and cut around it with a sharp knife. Smooth the edges of the clay with your fingers and some water if needed.
Let the clay coasters dry for a day.
Step 3: Sand and varnish the terrazzo coasters
Once your clay has dried thoroughly, inspect the coasters. If you find that there is a gap between the clay and the wood pieces, apply some glue or wood filler paste in the gap and let it dry. This will help you achieve a smooth and flat finish without any cracks.
When your coasters are ready, sand them down. I used a mouse sander but if you don’t have power tools, get a set of sanding sponges. Sand the coasters until the wood pieces are level with the clay and the top of the coasters is completely flat.
To finish, brush the coasters and wipe them down to remove any dust. Apply a few coats of clear glossy varnish, letting each dry well.
And you’re done, perfect coasters for a fresh spring tablescape!
