There are many ways to decorate pottery. For single pieces, the artist usually does this step by hand. They shape the piece and add colors to make a pleasing pattern. Sometimes they will add texture to a piece using different methods. There are tools specifically made to texture pottery. One of the oldest methods involves pressing natural items, such as leaves and sticks, into the piece when it is still pliable. This can make a pattern, or it can be just a highlight for the finished product. Texture and color can also be added by pressing on the piece with the hand. Pinching is a popular method used when making teapots or vessels that will pour liquids.
