Buy a piece of MDF and get it cut for you by your local DIY store to measure exactly 55 cms x 50 cms. When you get it home, draw a circle onto it with a diameter of 50 cms. This will become the outline for your coiled snake jigsaw. Then, make yourself a 慸rawing guide? This will allow you to draw two parallel lines in the shape of the snake body within the 50 cms circle. To make the drawing guide, cut a piece of scrap wood 7.5 cms wide by 10 cms long using your Dremel?Moto-Saw. Then, tape a pencil to each edge and draw the coiled body of the snake inside the circle. Create the head and tail by drawing them freehand.
