I have very basic tools but I make it work. I cut sections of clay using some fishing line that I found in the shed. I rolled my lump of clay into a bowl and then pinched a hole in the middle. I then pinched the walls of the bowl out making the bowl shape. I also used my fingers to shape the bottom of the bowl to get the thickness as even as I could. I scraped the uneven levels of clay off the top of the bowl to make it the same level. Cutting back the bowl with fishing line. I also used the fishing line in sections to cut back un even parts. After cutting back shaping the bowl. Shaping the bowl I then used other tools to start refining the shape of the bowl The finished product.
