Once the basic shape of the pet has been felted onto a wire armature, the 'top coat' of fibres can be added to create the true colour and individuality...You could say it is like painting with wool. 

I use many different fibres depending on the type of coat required...

Natural fleece, alpaca, camel down, mohair, silk, real dog hair, (I can even incorporate your own dogs combings)

I enjoy experimenting to find unique blends for my craft, including natural dyes.
