Yep, I did some spinning yesterday -- on my wheel. And it's funny that there should be a discussion of plying and balanced yarns on Theresa's blog today because I have been struggling with the same thing.
Yesterday I spun up this yarn, plied it & decided that there wasn't nearly enough twist in the yarn. So I plied it some more -- meaning put more twist into it. The resulting yarn was overly twisty, kinking up on itself. (I should have taken a picture -- doh!) But then came the "setting of the twist."
I let the hank soak in warm soapy water for about 20-25 minutes, then hung it up to dry with a bit of weight hanging from the bottom. This morning it was transformed into what you see above.
Here 's a comparison to show you the difference the plying can make:
On the right is my "old" plying and on the left is the new and improved plying. What a difference!
