Angelina Fibre
Angelina fibre is a really useful thing to use in your work. It is very quick and easy to use, all you have to do is lay out the fibres in whichever design you like and then use the iron to set the fibre. When ironed, Angelina can be cut with scissors and doesn't fray; it can also be melted/cut with the soldering iron. It comes in a large range of colours to suit whatever colour scheme you're using.
