Most of the tools are not very expensive but it is a good idea to limit yourself to a starter kit before you are sure that polymer clay is what you enjoy.
At first it might be a bit confusing to choose the necessary tools (at least it was for me) so I compiled a list for the beginners out there. Here are the tools that turned out to be most useful for me:
1. Pasta Machine
As weird as it may seem, pasta machine is the most useful tool you can get. It serves to warm up and soften the clay, create uniform sheets of clay (of different thickness), blend colors, and many other purposes. A good place to buy pasta machine is on ebay. You should not invest in any high-end pasta machine because you should never use this machine for food preparation. The cheapest one will do just fine.
2. Cutting and Sculpting Tools
To create detailed ornaments, you will need to use cutting tools. I mostly use these 5 tools.
1) and 4) Sculpting tool and doll making needle. Useful for connecting pieces of clay together, moving and fixing small pieces of clay onto the project, sculpting little holes, etc.
2) and 3) Modelling knives. Can be used for moving and fixing elements onto the project. They are also good for cutting shapes and small elements.
5) Slicing blade. It is used for cutting slices of canes and blocks of clay. It is also flexible so that it allows you to create different shapes.
Another essential tool is an acrylic roller. You will use it to flatten your pieces, roll in cane slices and many more. Before I got my acrylic roller I was using a small wine bottle. But the problem with a glass bottle is that the clay can stick to it and your projects can get ruined.
4. Cookie Cutters
Ok, so they are not absolutely necessary but still very fun to have. You can of course shape your pieces by using knives and blades, but cookie cutters are handy and will make your job easier.
5. Examination Gloves
And last but not least, examination gloves. They will help to protect your skin and keep colors of clay separate and clean. Thanks to the gloves you will also be able to keep the surfaces of your clay projects clean of fingerprints. Just make sure that you buy a tight fit for your hands.
