How to make Clay That looks like Polymer Clay

by

You can actually make your own polymer-style clay at home, and the best part? You don’t need any fancy supplies. With just a couple of everyday household items—cornstarch and white PVA or Elmer’s glue—you can whip up a batch of soft, moldable clay that behaves a lot like store-bought polymer or Fimo clay.

This homemade clay recipe is budget-friendly, kid-safe, and perfect for crafters who want to experiment without investing in expensive packs of clay. Unlike some other DIY or air-dry clay recipes, this one dries to a smooth, pure white finish with minimal cracking, making it a great option for handmade ornaments, jewelry, small figurines, or keepsakes.

Think of it as the ultimate rainy-day project supply—you can mix it up in minutes, store it in the fridge for later, and then shape it into just about anything your imagination dreams up. Whether you’re crafting with kids, prepping for holiday decorations, or just want to test out clay sculpting without running to the craft store, this simple recipe has you covered.

This polymer clay tutorial shows you how to cook the glue and cornstarch to create a dough-like substance that will effectively dry in the air. So an air drying polymer clay.  Similar to white Airdrying clay but of course far more affordable!

You can also paint the clay and seal it with high gloss sealer. It is also referred to as cold porcelain for its smooth white finish.

You might be surprised to know that it also contains lemon juice.

The Etsy team at New York has put all the details and instructions together: Homemade Polymer Clay.

  2. Hi! You’re correct in that traditional plastics based polymer is heat cured but a lot of the air dry clays are lumped in with the polymer clay category in terms of tutorials, tools, their location at stores and their market. So my manager thought the recipe appropriate and posted it.

    It makes a nice air dry modeling material that has a texture similar but not quite like air dry “porcelain” clay. I imagine homemade polymer clay of the type I (and probably you!) work with would be more of a combination of heat set glues and pigments and binding powders rather than air dry glues and pigments and powders. One just polymerizes at a very different temperature / condition than the other.

  3. Just made a batch and only issue was food coloring isn’t bright enough so I hope to test one more batch with pure pigment

DIY Pottery Clay Sardines with Hand-Drawn Designs

If you’ve ever walked through a Greek market, you’ll know the charm of sardines lined up fresh on ice. This project brings that same coastal energy into your home, but with clay instead of fishy fingers! These glossy ceramic sardines are simple to make, fun to decorate, and can be strung up as ornaments, kitchen wall décor, or even Mediterranean-style gifts.

Whether you use earthy pottery clay or an easy air-dry alternative, these sardines look stunning with their hand-painted red and blue designs. Think seaside tavernas, olives, and a glass of wine while you create—a craft that feels like a holiday.

Why Make Clay Sardines?

  • They’re a beginner-friendly pottery project. 
  • You can decorate them with bold, folk-art patterns in classic coastal colors. 
  • Add a little hole and string, and you’ve got instant hanging ornaments. 
  • They make wonderful kitchen décor or handmade gifts. 

Materials You’ll Need

  • White pottery clay (stoneware or earthenware works best) 
  • Rolling pin 
  • Sardine printable template (available from Craft Gossip) 
  • Craft knife or needle tool 
  • Wooden modeling tools 
  • Small bowl of water 
  • Underglazes or ceramic paints in cobalt blue and terracotta red 
  • Fine paintbrushes 
  • Clear glaze 
  • Twine or rustic string 
  • Kiln (or air-dry clay if you don’t have kiln access) 

Step-by-Step Tutorial

Step 1 – Roll Out the Clay

Roll out your clay into an even slab about 6–8mm thick. Use guides to keep the thickness consistent.

Step 2 – Cut the Sardine Shapes

Place your sardine template on the clay and trace around it with a needle tool. Cut out as many as you’d like—bundles of 5–6 look fantastic.

Step 3 – Smooth and Add Details

Gently smooth the edges with a damp sponge. Use a tool to press a tiny hole in the tail end—this will allow you to thread string later. Add light details like fins or eyes if you’d like, but keep it simple.

Step 4 – Dry and Bisque Fire

Let your sardines dry slowly under a cloth for a day or two, then fully dry before bisque firing in the kiln. (If using air-dry clay, skip the kiln and let them cure naturally.)

Step 5 – Paint in Red and Blue Designs

Once fired, bring them to life with underglazes or ceramic paints. Use bold, simple folk-art patterns such as:

  • Wavy lines for the sea 
  • Stripes for a nautical feel 
  • Leafy spines down the middle 
  • Dots or chevrons for variation 

Keep each one different so they look like a joyful, mismatched family of fish.

Step 6 – Apply Glaze and Final Firing

Coat the sardines with a layer of clear glaze to give them a beautiful glossy finish. Fire again according to your glaze instructions.

Step 7 – String and Display

Thread rustic twine through the tail hole and tie into loops. Hang them in bundles on the wall, string them along a shelf, or gift them to a friend who loves coastal charm.

Ideas for Using Your Clay Sardines

  • Kitchen Wall Hanging: Group 5–6 sardines together for a bold focal point. 
  • Christmas Ornaments: Folk-art sardines make quirky, coastal tree decorations. 
  • Gift Tags: Tie them onto a wrapped present for a handmade extra. 
  • Table Styling: Scatter them across a breadboard or tray for a Greek-inspired tablescape. 

Don’t stress about making them “perfect.” The beauty is in their handmade irregularities—slightly uneven shapes, brushstrokes that wander, and rustic twine ties. That’s what makes them feel authentic and special.
