Plying wool for socks

I spun two half-bobbins of wool with the wheel moving clockwise, and then plyed the two together with the wheel moving anticlockwise, to give a smoother, stronger yarn. This is my second attempt at spinning for the socks I have in mind. The first lot wasn't thin enough. I suspect I was in too much of a hurry to put my idea into practice!  I plan to dye the wool today. The sun is shining so it will dry quickly and then I can start knitting.
