What is polymer clay?

So, what is polymer clay? Polymer clay is a type of synthetic clay that can be "set" or hardened, by baking it in a domestic oven. There are lots of different types of polymer clay to choose from, and you'll probably have heard of the most popular brand here in the UK - Fimo.

In the US, Sculpy is a popular choice for modellers. As well as a huge range of colours, you can also get glitter, translucent, metallic and even glow-in-the-dark polymer clay!

Polymer clay is a colourful and versatile modelling material. It’s a perfect way to create your own stunning designs using some fascinating techniques and effects. Polymer clay can be baked in an ordinary oven to set it permanently hard. Baked polymer clay is durable and strong which makes it an ideal material for creating handmade jewellery, decorations and models.

Working with polymer clay is a tactile, absorbing and uplifting process. It’s suitable for all ages and abilities and is easily adaptable to different styles. Polymer clay can be used in a simple way or, for more complex and advanced detailed work. The possibilities are endless for making your own exciting polymer clay creations!

If you're after all the colours of the rainbow then this is the polymer clay kit for you. There's everything from neons to pastels and they're all contained in this handy box to keep things neat and tidy.

What is polymer clay used for?

Polymer clay is extremely light in weight, making it an ideal medium for making jewellery, ornaments and decorations. If you're into making your own jewellery, or perhaps have a side hustle, then it is also brilliant for making beads. And by mixing colours together to create a marbled look for your polymer clay creations, you can even evoke the look of Venetian glass - try it with blue and white clay!

Top tips for using polymer clay

  • Clean your hands between colour changes for neat designs
  • You can still cut and shape the clay after baking, as it won't be hard until it has cooled down
  • Line your baking tray with some aluminium foil before baking, to prevent your miniature masterpieces from sticking

Polymer clay for beginners

First - layout your working area. Make sure your surfaces are protected, as little bits of the clay can all-to-easily find themselves trodden into the carpet. Grab your rolling pin, some modelling tools and your polymer clay.

If you have one, use a large ceramic tile or baking sheet to work on, as this provides a smooth surface (and therefore a smooth finish to your clay). Acrylic rollers designed for polymer clay are smooth to use and easy to clean.

There are lots of fun techniques to explore to make polymer clay patterns, including blending, marbling, multi-coloured surface effects. A pasta machine is a quick way to roll polymer clay into a flat sheet!

Patterns and effects can be added to polymer clay using paints, gilding wax or other materials. Try enhancing the surface with a texture sheet or use gilding flakes (or metal leaf) for a flecked foil effect. Shaped cutters and silicone moulds are a quick and easy way to make multiple shapes.

How to use polymer clay

Now you know the basics, let's get started making a project!

Polymer clay is brilliant for rustling up a side hustle - in this easy beginner tutorial, we show you how to make three different species of polymer clay fish. We've turned them into light pulls, but they could just as easily make cute keyrings or pendants. There’s clownfish, angelfish and pufferfish, but you can easily custom-make versions to match different bathroom colour schemes.

These fish will sell themselves with their cheeky facial expressions and tropical colours and will make an attractive display on your craft stall or website, so make sure they are arranged well to maximise sales. A versatile make, you can easily create smaller versions of these fish to wear as pendants or earrings, giving you an instant jewellery range, too!

You will need:

  • Plastic polymer clay tools
  • Craft knife
  • Three wooden kebab skewers
  • Three light pull cords
  • Baking tray

For the puffer fish:

  • Fimo Polymer Clay in Pacific Blue, Sunflower, White and Black

For the orange clownfish:

  • Fimo Polymer Clay in Tangerine, Tropical Green, White and Black

For the angelfish:

  • Fimo Polymer Clay in Raspberry, White, Peppermint and Black

How to make the pufferfish

Step 1

How to use polymer clay – polymer clay for beginners, pufferfish step 1

Roll up a 60g ball of blue clay to make the body. Follow step 2 of the clownfish light pull to make the eyes, but make them with wonky pupils for added character! Make a divet under each eye for the cheeks. Roll up two 1cm (½in) balls of blue clay and press into the divets so they are slightly flattened. Use a blunt knife to cut a round hole between the cheeks for a mouth and fill it with black clay.

Step 2

How to use polymer clay – polymer clay for beginners, pufferfish step 2

Roll up two small balls and one larger ball of yellow clay. Use your fingers to flatten all three balls of clay, then shape each one into a fin – use the smaller balls to create two side fins and the larger one to make a tail. Use a craft knife to cut a spiky shape into the ends of the fins and tail. Score lines onto each side of the side fins and put to one side to use later.

Step 3

How to use polymer clay – polymer clay for beginners, pufferfish step 3

Make a divet in the back of the fish’s body for the tail. Push the end of the tail into the divet and blend with a blunt knife until it sticks to the body. Score lines on both sides of the tail. Use a flat tool with a curved or triangular-shaped end to press randomly all over the fish’s body to create a scale texture.

Step 4

Push a kebab skewer through the body of the fish from the top to the bottom. Hold the fish on the skewer while you make small divets all over the body for the spikes. For each divet, roll up a small ball of yellow clay and press into the divet until it sticks. Attach the side fins by pressing the ends onto the body until they stick.

How to make the clown fish

Step 1

Roll 50g of orange clay into a ball and shape into a fat teardrop shape for the body.

Step 2

Pinch the end to make a tail, shaping it with your fingers and a rounded tool. Bend the tail slightly to one side to make it look like the fish is swimming. Score lines into both sides of the tail.

Step 3

Roll two balls of white clay to 1cm (½in) to make the eyes. Push them into the dips in the face so that they stick in place. Make a small divet in each eye for the pupils. If you want your fish to have a cheeky facial expression, then position the pupils so they look to one side. Roll two balls of black clay to about 2mm, then press them flat. Push them into the pupil holes on the eyes so that they stick in place. Use a craft knife to cut a smiley mouth into the clay, below the eyes, then fill the mouth with black clay.

Step 5

Make a long thin sausage from white clay and press it flat with your fingers to create a stripe. Position the stripe around the fish’s body behind the eyes, and cut to fit. Position another white stripe near the tail and cut to fit. Press the stripes so they stick to the body. Repeat this with the green clay, positioning the stripes so they slightly overlap the back of the white stripes.

Step 6

Roll up three small balls of orange clay and press them flat with your fingers. Shape two of them into a side fin shape and use a blunt knife to score lines into the clay. Place the side fins onto each side of the body and blend the ends of the fins into the body with a blunt knife until they stick. Shape the other piece of orange clay into a back fin and attach to the top of the body, blending the bottom of the fin into the body until it sticks. Use a blunt knife to score lines into both sides of the back fin.

Step 7

Buy now: £10.99, Amazon

Polymer clay needs to be baked at a very low temperature to set it permanently hard. Carefully lift models onto a baking tray or tile, or if it’s suitable, transfer the tile or tray you’ve been working on straight into the oven to avoid lifting your work. Always refer to the manufacturer’s instructions for baking as there are slight variations on specific temperatures for the different clays. The temperature required is usually between 110oC – 130oC for around 30 minutes.  It’s useful to have a thermometer to check your oven temperature.

4. Clay modelling tools

Tissue blades are commonly found in polymer clay blade sets, and they’re used for cutting extremely precise, straight lines, usually through a stratacut block or similar. Because the blades are so thin, they are also flexible and can be bent to create a gentle curve. Because these blades are so thin – it is also very sharp, so please note this is not for children and should be kept in a sealed container when not in use.
