These Geometric DIY Cork Coasters are one of our most popular home decor posts of all-time, so you’re in the right place for a quick weekend craft project or gift idea!

Hello, fellow DIY enthusiasts! Teri of the Lovely Drawer here!

Today’s project is oh so simple but has maximum impact for entertaining or just a casual rendezvous over tea for that matter.

These Geometric DIY Cork Coasters pack a punch and can be used individually or slotted together to create a patterned trivet for serving.

It’s basically the cutest (and easiest) puzzle you’ll ever see!

Coasters can be dull, but these will add a pop of custom color to your table. And I can vouch that once you’ve made one, it’s absolutely addictive!

Plus, these are extra unique with its hexagon shape. And of course, judging from our previous DIY’s, we have a thing for hexagons like with our Hexagon DIY Leather Vanity Trays and Hexagon DIY Marble Serving Boards.

They also make great gifts for the holiday season too.

Why not package up a stack with a matching ribbon and spread some patterned cheer?

Materials and Tools Needed to Make DIY Geometric Coasters

PDF template — To make the whole tutorial even more straightforward, I made a downloadable scaled template for you to use.

Craft paint – In 2 colors or mix your own.

Cork tiles 1/4″ thick — I used cork tiles that are 1/3″ inch thick as a base to make sure the coasters didn’t curl up at the edges. But anything above 1/4 of an inch thick should be fine.

Rotary cutter or craft knife

Cutting mat

Washi tape

Paint brush

Cardstock

Pen

Optional: Mod Podge in matte — Or any other water based sealer to protect your coasters

Home Decor DIY Idea | How to Make Easy DIY Geometric Coasters

1 — Start by printing out the hexagon template onto card and then cut around the outside with a scalpel/craft knife.

Use this to draw around with the pen, onto your cork sheets.

2 — Cut the hexagons out using the scalpel/craft knife. Repeat this step for each coaster. Make sure the blade is sharp otherwise you’ll get rough edges.

3 — Now mask off an area that’s equivalent to a third of the hexagon with the washi tape.

Follow the photo, taking the tape from the outer points to the inner point. You can measure where the middle is to start with if you’d prefer.

4 — With this shape taped out you can get painting the third of the hexagon that’s exposed.

You will more than likely need two coats to get a vibrant color but make sure you leave each coat to dry before applying the next.

5 — Remove the the tape once dry and then mask out another third with some more tape.

If you make sure that each color stays on the same side of the shape then the colors will fit together perfectly.

I kept the peach on the left and the orange on the right. You’ll need two coats of paint to fill in this second shape on each too.

5 — Once totally dry peel away the second lot of tape and there you have a new set of geometric tessellating coasters!

6 — Optional: For extra protection, you could apply a coat of clear matte Mod Podge.

Now that you’re swimming in colorful coasters, get them out on the table and dotted around your home to save your surfaces.

Nearly every surface in my apartment is white so I’m looking forward to putting these to good use and no longer having rim marks glaring back at me.

The perils of a love affair with white!

Pre-warning: your kids may well steal coasters if they get ahold of them as thinking about it, they look like a pretty fun game through the eyes of a 3 year old.

If these DIY Geometric Coasters go missing you know where to look first. That advice is for free ;)
