Marbleized Polymer Clay Coasters

Decor, DIY, How-Tos

These marbleized polymer clay coasters are so fun and easy to make! Like so many of my other DIYs, such as the Glass Hurricane Lamps, the Wood Bead Cake Stand, the Mercury Glass Candle Holders, the Tiered Tray Jewelry Stand, and the Concrete Bowls these coasters are another wonderful handmade project. They are not only beautiful but functional too… My favorite kind of DIY!

The best part about these coasters is that you can make them suit your style. The colors you choose to use for the marbling are up to you. If you like bold colors, go bold if you prefer pastels or neutrals, perfect. These coasters are beautiful in black and white too. Add some glam with metallic polymer clay. The sky is the limit! Most importantly, have fun, get creative, and make these DIY clay coasters your own. They will look beautiful and be perfect to use in your home, I promise.

What is Polymer Clay?

These beautiful DIY clay coasters are made with polymer clay. I first discovered this special kind of clay when I made my Clay Heart Trinket Dish. Polymer clay is an oven baked modeling clay composed of polymers, resins, and coloring agents. It’s widely used by artists and hobbyists for all different types of projects. One of the many reasons to love polymer clay is the vast amount of colors it comes in. The beauty of polymer clay is that it’s incredibly moldable, never dries out, and it hardens perfectly when baked at a low temperature in the oven. It can be found at most craft and art supply stores. I prefer the Sculpey brand. 

Supplies Needed to Make Marbleized Polymer Clay Coasters

Materials needed to make DIY polymer clay coasters including clay, round cookie cutter, a rolling pin, paint, and a paintbrush.

  • Polymer clay (in the colors of your choice, but use 2-3 colors)
  • Rolling pin
  • Circle cookie cutter (at least 4” in diameter)
  • Baking sheet
  • Parchment paper
  • Acrylic paint (I used gold)
  • Paintbrush

How to Make Marbleized Polymer Clay Coasters

Step 1: Roll and Shape the Clay

Roll the clay into long thin rods using two to three colors. Three colors are ideal. Each rod should be about 6-8 inches long. One rod should be about 1 inch thick, while the other color(s) should be about 1/2 inch thick. Gather up all the rods and gently begin to twist them together until the colors begin to blend. Roll the twisted rod on a flat surface creating one long rod.

Step 2: Create the Marbling

Fold the long rod in half and then twist the halves together. Roll into a rod again. Repeat this another couple of times until satisfied with the marbling. Be careful not to roll and twist the clay too many times, otherwise, the colors will get muddled together. I found that about four times gave me the marbling effect I liked best.

Step 3: Making the Coasters

With your hands, roll the clay into a ball and then use a rolling pin to flatten out the ball until it’s about 1/4-1/2 inch in thickness. Press the circular cookie cutter into the clay and place each circle on the parchment-lined baking sheet. Bake the coasters in the oven according to the clay package instructions. Allow the coasters to cool completely once they are out of the oven.

Finishing Touches

If there are rough edges on the coasters, use fine-grit sandpaper to smooth them out. Using a small paintbrush, paint the edges of the coasters to add a beautiful finishing touch. I used gold paint, but you can use copper, bronze, silver, or any color you like.

To Seal or Not to Seal

Polymer clay does not need to be sealed. Once baked, polymer clay is durable plastic and therefore even more durable than any sealer. If you want the coasters to have a glossy finish, you can seal them with a Mod Podge Dishwasher Safe Gloss formula coat. I did not seal my coasters and they are holding up beautifully.

What Else Can I Make With Polymer Clay?

Thank you for asking! The short answer is, “The sky’s the limit!” As you can see below, I have made trinket and jewelry dishes, candle dishes, and coasters all from polymer clay. Next, I want to make a ring dish. It’s been so fun creating beautiful and useful small gifts for myself, friends, and family with this special clay.

          Hi Lynn! Thank you for stopping by and checking in. My family and I are very well. We have been soaking up summer and traveling a lot. We’ve been to Virginia, Costa Rica, and the Bahamas. Lots of great memories have been made that we will cherish forever. Life is good. I miss y’all too, though I must admit, the break from social media has been heavenly. I hope you and yours are well and that you are still enjoying life in Australia. I appreciate you thinking of me!

  2. Kelly Bontrager says:

    • Meeghan says:

      Thank you so much, Kelly! I’m so happy you like them. I appreciate your kind words and compliments too. I am doing well, thank you. I hope you are too!

  3. Lauren Smith says:

    Sure miss you on Instagram. How are Willy and all the other babies doing?

    • Meeghan says:

      Aw, thank you, Lauren! It was time for a break from Instagram. Although I don’t miss the rigor of the app, I do miss y’all. I have been keeping myself busy with pottery classes, learning how to bake GF artisan bread, doing yoga, gardening, traveling more, working on the blog, and of course- taking care of the animals. Willy and the crew are all doing great! Thank you for asking. I hope you and yours are well. I appreciate your message.💛

    Absolutely beautiful!

  5. Kelly says:

    Love the coasters. Do you have to have a designated rolling pin and cookie cutter or can they be the same as the ones I use for baking? Thanks!

    • Meeghan says:

      Thank you, Kelly! I do have a designated rolling pin and cookie cutters for my clay projects. I recommend that y’all do the same, just to be safe. Have fun creating!

  6. Elaine Lindsey says:

    Hi Meeghan sure do miss you on the gram think of you always thought about writing a letter to you hope your family is well and Willy is behaving I miss those farm animals and all your DIY’s miss your smile hope you’ll come back one day Elaine

    • Meeghan says:

      Hi Elaine! Thank you for popping by and saying, “Hi!” It’s so good to hear from you. I miss y’all too. Instagram has changed so much since I first started my account there. In the last year or so it just hasn’t felt like the right fit for me. It’s all getting too fast, taking too much time away from “real” life (a life that I absolutely love), and I no longer wanted the distraction in my life. It was a difficult decision to temporarily disable my account, but it’s the best decision I could have made. Although I miss all of you, I don’t miss the rigor or distraction of it all. Life is SO good. I’ve been keeping myself very busy! I’m not sure if or when I’ll be back on Instagram, but I’ll always be grateful for my journey there. I feel very lucky to have connected and hopefully inspired many like you during my time there.

      My family and all the animals are very well. Willy is staying out of trouble and still enjoying his treats, as are all the animals. I hope you and yours are doing well too. Hopefully you will continue to check in with me here, I would love that. I appreciate you thinking of me and reaching out.💛

  7. Bobbie Lutz says:

    Oh, how good it is to find you doing well! I’ve really missed you but can certainly understand what you mean about IG! So much pressure to do so much! Hope your family is doing great … the animal babies too!

    • Meeghan says:

      Hi Bobbie! Thank you for stopping by and saying, “Hi!” It’s so nice to hear from you. I am very well, though I miss you too. We just got back from Costa Rica and it was an amazing trip. I’m still thoroughly enjoying my break. 🙂 My family and the animal babies are all well, thank you for thinking of us all. I hope you are having a wonderful summer so far!

  8. Laura Skidmore says:

    Hi Meeghan.
    I was so happy to see these comments today. I have been wondering how you and your family were doing and so glad that you are doing well.
    I am gluten free so would love to know how the bread making is going. Fun for you to go to Costa Rica, one of our favorite family trips!
    Great to know you are well. Miss seeing you, the farm and animals!
