Portable Supports

There are two types of portable supports-stretched and unstretched. A stretched support is a material, such as canvas, stretched over a frame or panel. Unstretched supports are plywood, fiberboard, particle board, metal, paper, board, and even canvas without a frame. The purpose of having a portable support is to be able to move it easily from place to place. Therefore a support’s most important characteristics are that it be lightweight, stable, and durable. Often these factors must be balanced among one another.

For example, if the support is too lightweight it is often not stable. And, if it is made to be very durable it is often too heavy. Each situation is unique and requires its own balancing act.
