You can make very interesting snail figure out of the flat metal bar and nuts and washers, which you can easily fasten with screws on the wooden pillar of a pergola or any other place in your garden or on terrace.
To create this interesting garden snail, beside a welding machine, a drill and various hand tools, you will also need scroll bending tools.
150mm (5.89'') x 100mm (3.92'') x 37mm (1.47'')
A scroll is a metal strip or rod that is bent to have a spiral shape. It is one of the most common decorative elements in making items from wrought iron. Scrolls can be hand-crafted, but much greater speed and precision is achieved using scroll bending tools (scroll bender, scroll machine, scroll bending attachment...).
You can paint the snail anyway you like.
