My homework is complete for Saturday's class leaving four skeins of yarn ready for the dye pot. Making a two-ply yarn takes some work in getting a balanced twist. The singles are spun clock-wise and then you ply them together with a counter clock-wise spin. I had an ah-ha moment when everything clicked and I could pull the yarn back from the spindle and it hung gently instead of twisting back onto itself. That's a balanced twist. Another test is if the yarn hangs straight. I should get an "A" on both.
