Step 1: Draw a rough sausage shape with free hand in faint curve. Do not stop the curve in the middle, continue until you meet the starting point. Step 2: To give a sliced sausage look, draw one more curve as shown. Line inner side with another faint curve as shown. Step 3: Erase the inner line leaving the faint impression and mark the posit...
