Polymer Clay Earrings: From Block to Boutique in One Afternoon
Polymer clay is the most forgiving jewellery material there is. Mistakes can be re-kneaded. Colours can be blended. And the finished pieces look like something you'd pay £30 for in a boutique.
What You'll Need
- Polymer clay in 2–3 coordinating colours
- Acrylic rolling pin or clay roller
- Clay cutting shapes (arches, circles, ovals)
- A craft knife or tissue blade
- Baking parchment and a baking tray
- Earring posts, jump rings, and pliers
- Sandpaper (400 and 800 grit) and a little water
Step 1: Condition the Clay
Warm the clay in your hands and knead it until it's soft and pliable — about two minutes per colour. Cold clay cracks; warm clay behaves.
Step 2: Roll and Cut
- Roll the clay to an even 2 mm thickness. Use two stacks of playing cards as a guide rail for your roller if you don't own a clay machine.
- Press your cutters straight down — don't twist, or you'll distort the shape.
- For a marbled look, twist two colours together 3–4 times, then roll. Stop before it turns muddy.
- Smooth the edges with your fingertip or a tiny bit of water on a cotton bud.
Step 3: Bake
Bake on parchment at 130 °C for 30 minutes. Always check your clay brand's instructions — temperatures vary. Let pieces cool completely in the oven before touching them; they're brittle while hot.
Step 4: Sand and Assemble
Wet-sand the edges with 400 grit, then 800 grit, until they're glassy. Drill or pierce holes before baking if you're using jump rings. Attach posts with strong jewellery glue and let them cure for 24 hours.
Pro tip
Bake your pieces on a bed of cornflour to stop them slumping and keep them perfectly flat. Brush it off afterwards with a soft brush.
