I've concentrated hard, honestly I have, but not hard enough it seems!
First of all, the good news is that since deciding to make a swallowtail shawl, I've been spinning more 'wheatfield' yarn, and achieving a very consistent and fine yarn (20 wpi). I've been using my drop spindle for this, as I think it gives me more control, and I've found the return to the drop spindle most enjoyable. The cute centre-pull ball in the picture I wound using my new nostepinne - I'm so grateful for this lovely gift from my sister who, among other things, now turns wood.
But back to concentration. I'm not sure whether you can see from the picture, but I've made a cock-up in the pattern (on the left in this picture). I've pulled out a couple of rows and tried to continue from there, but it's still not right. I've got to pull out again and go back a bit further.
I suppose two steps forward and one back still = progress!
