A good starting point for a model is a scale sketch or marquette. Once the design has been established, the 'skeleton' can be added to a full size sketch which will help determine the size of the armature framework and where any joints will occur. The image below shows a sketch of the framework which will be used to make a paper mache dog (find our more from Ultimate Paper Mache).

Aluminium is ideal for use as an armature because it is very flexible and lightweight and does not rust. The mesh can be moulded around a shape or manipulated with pliers and provides an excellent support for most modelling materials. An impressive example of a model created using modelling mesh can be found on Tom M Jordans Art Page.

The image below is taken from an in depth step-by-step tutorial by Setti Fine Art on how to build an armature for a clay model. It shows how to create the wire framework, stabilise it with rock hard, air drying epoxy resin and how to mount the armature onto a sturdy base before building up the model.

A wire armature is ideal for making poseable needle felted figures or animals. As the fibre cannot be felted directly onto the wire because it can break the needle, the wire can be wrapped with pipe cleaners, yarn or strips of vilene wadding to provide a base to work on. Sarafina Fiber Art - who have a series of YouTube videos on needle felting - shows how to make a needle felted fox using an armature.
