This was an interesting exercise. Both skeins are 100% yak with singles spindle spun supported at the same time. BUT left one was plyed end of last year using my usual method matching the ply twist to the singles twist on my plying drop. Meanwhile the right one was plyed recently on the drop except singles were released slower which allowed way more ply twist to build up – I think this resulted in a much nicer & plush yarn for this fibre.
So, since yak is uber expensive I decided to unply/re-ply the left skein & it turned out really nice!
Also, wow! Different weather lighting really drastically changes hiw the colour shows up huh?
