it seemed every row of the little lice/ white dots, my white/ natural wanted to be tighter than the gray. sort of giving me squinty small dots. Each 12 stitches is a repeat. Each of my repeats is seperated by a marker. I do one repeat as given, the next one , for one of the dots i do a yarn over, k1 with the white. that gave me the little bit of extra white yarn in the yarn over.
on the next row , all gray, i drop the yarn over, knit the white stitch with gray.
the dropped yarn-over loosens up my tight white yarn tension just enough. it does not show at all for my own tension. it gives me one yarn over worth of extra yarn every 24 stitches, not too much, just enough.
