I spun from a large bag of Polwarth Luxury Blend (Polwarth blended with cashmere, baby camel, yak and baby alpaca) from Spirit Trail Fiberworks. I didn’t split the fiber into piles. I didn’t weigh the fiber nor the bobbins. I just spun until I thought I was about half way through and switched bobbins.
What you see on the left is what was left on one of the bobbins after I finished plying — about 30″.
I can’t get this close when I try to split the fiber evenly into 2 batches. Perhaps I should just stop trying so hard, eh?
