How to make a nuno felted infinity scarf

I find these very comfortable to wear as they stay put.
I started with a length of dyed scrim 73 inches by 14 wide. If you divide your wool fibres in half it helps to get the two sides equal
I had sewn the two ends together.You can use any fine fabric such as silk of silk chiffon or muslin and scrim.To stop the two layers from felting together I put a piece of builders plastic between the two layers.I then laid a layer of wool fibres on the top.If you want a thicker scarf you could lay two or three layers remembering to alternate the way in which they are laid downI laid some red tencel fibres on top for some colour and sheen
