Felting ,Basically, it is the process of turning a protein fiber (meaning animal fiber) such as sheep wool, alpaca, mohair, yak, etc. into a piece of fabric by connecting the individual fibers.
The wool can be in any form from raw locks to processed roving or batts and there are several different methods of accomplishing this felting process.
What is the process of felting?
Hot water, sometimes with added soap, is sprayed onto layers of wool, while repeated agitation and compression causes the fibres of the wool to hook and weave together into a single piece of fabric.
Only certain types of fibre can be wet felted well.
