A black woolen fabric with a very long nape. It is coarse and heavy. When stretched the fibres tighten and become water resistant. There are two seperate catagories, Heat Bondable and Non Heat Bondable: both can be freely added in small quantities to give sparkling highlights. Both types work well in combination in small amounts with other fibres either handspun, wet felting or needle felting. A little goes a long way.
