Shade cloth sails on steel poles are the simplest form of fabric structure, but they still can be aesthetically very pleasing. In this example by Irymple Canvas, over the Merbein Public Pool, shape and colour complement each other to create a striking structure.

One clever feature of these sails is where sails have a triangular shape in plan, they actually are four sided sails, with two connections to the one pole. These twisted four sided sails maintain their pretension better than simple triangular sails, and seem to look better.
