I learnt a few new techniques at the course by Laura Thomas. False leno, a technique which involves incorprating random skips into tabby which produces a nice textured effect and a bit of fulling. The photo below shows my samples after being put through Laura's washing machine at 60 degrees. They have shrunk by 50%. The effect is rather nice and I will try this again to which end I bought some of the same lambswool as Laura uses.
The draft is of three blocks and floats of lambs wool have been created which, when washed and shrunk, pull the bamboo/cotton warp up. I like the one at the bottom best. I threw a weft of bamboo/cotton with every weft of lambs wool so that is pulled up into little loops. It feels really soft.
