Basically you make a "clay sculpture". You then make a "clay sculpture tool" and to switch between the modes you craft the tool by itself again. Some tools have secondary actions, for example "Move" has "Stretch" which you get by crouching and pressing RMB.

Place the clay sculpture and start working with the tool. If you want another layer you just right click the sculpture with a clay ball. You can switch between them with the "Select" tool. The sculpture can not be more than one block large.

I got this information by using Google. Here's a full quote: The clay sculpting tool is crafted with a bit of clay on a stick. Different classes of tools can be gotten at by crafting the tool by itself. And there's a second layer of tools that you can get at by shift-right-clicking the ground with them. In most cases the opposite effect (rotating the other way, or stretching the other way) can be gotten by holding shift while using. Another lump can be added by clicking on the sculpture with a clay ball. A single lump can't be larger than 1m³. They can be moved out of the sculpture's block, but must stay within the 3³ area. The purple tool selects a clay lump, and the currently selected lump is drawn slightly purple. Right click on the sculpture with wool to dry it up. Sculptures will also dry if they aren't handled. There is no firing or glazing at this time.
