To prove my point I want to show you how sculpting (my forte') can be done and done well with just stuff you find in the kitchen. If you were to expand your tool search into the rest of the house...
Well, you would have a literal warehouse of implements.
To begin creating a satisfying sculpture that will last and that you can show off I will suggest buying one thing and one thing only: a box of polymer clay.
Yup that's it.
With just a box of clay most people have everything they need to create at their kitchen table. I mean let's face it, with sculpting I may be picking an easy subject because honestly with just your hands alone you could create something. But I am sure most of you want to add details, or textures, or some smooth flat surfaces and using a tool to do that is a lot easier.
