I chose a circle for my smooth coil pot. I chose a circle because I wanted to make something where I could keep things. I can put like my pens and pencils in my smooth coil pot it will hold them in their. I made this smooth coil pot by making coil after coil and placing them on top of eachother. I scratched and attached each coil on to make sure it would stay on. I smoothed it so you could not see the outlines of the coil it just looked like one big pot. A good coil pot is smooth and even. It stands sraight up and does not have any cracks.
