Modelling is not difficult, but it require patient and time. Think in something easy and nice, model it, put it into the oven (better using Polymer Modelling Compounds) and later, you can even paint it.
Use special clay that allow you to use your home oven, and buy special painting that work on the material you choose. Start with something easy like a plate or vase.
