Wool is sometimes the wrong fibre choice because moths and carpet beetles like it too much. I like to manage risk, not court ruin. So, there's linen. It would be ideal to spin by hand all the yarn I use, but I don't spin linen yarn yet.
A long-time weaver was selling her extras. I got these two cones of vintage burnt orange on the off-chance that the yarn might suit a future project, a språng wall-hanging that someone in my family has requested I make.
