I call them yarn turds.

I spun this a while ago from two different dye lots of unsold braids of brightly dyed merino wool.  The colours were fairly clashy so I was expecting drama but they toned and mellowed each other out beautifully.  This yarn is super soft and the turds (stacked coils) sexy up the texture.  This will be a scarf where every third stitch will be dropped to create a run that should give this scarf a lovely, light, lacy feel when finished.
