Here is that batch of varigated pinkyarn that I spun up-all knitted up. I washed it in my hair shampoo (Dove 2-in-1) and it felted up nicely. Not too much, not too little. It did not take much work at all nor did it take much to remove the suds. I've go it pinned to an old scanner box and now it sits in the sun to dry. When dry, I will measure the STI for size 7 needles.
