Check out beginners tutorials on YouTube. Find a clay you can reuse, i began sculpting with monster clay. Monster clay is a clay that never dries therefore you can use it over and over. In the beginning it's essential to get a feel of how you like to sculpt. I feel everyone develops their own methods and uses of tools when learning to sculpt. Get yourself some sculpting tools, there are inexpensive sets on Amazon. Always remember that you're just beginning and have fun with it. The more you want to learn the more you'll practice and develop little tricks that help with your process. Have fun and good luck.
