I'm currently researching available sustainable fibres besides wool. The photo is of a fabric that I made a few years ago using a yarn made from seaweed and alpaca. It was ultrafine and had a lovely soft handle.
First though, I have to use some of the existing stack of wool and wool mixes!
Wow, that new material is amazing! Can’t wait to see what you make with it 😍 Good luck with your move.
