What is Greasy? This doesn't sound nice!
Don't
worry, this only means that the
lanolin and the processing oil, an absolute requirement
during the manufacturing of the yarn, has not been washed out.
This is normal practice as it allows the knitter or weaver full control
of the finished quality they want for their end product after scouring
(washing) and drying.
What is Clean? This sound nice!
Hand Knitting Yarns tend to be
scoured to get the processing wool out so its nice and soft when knitting by hand. Our hand knits are scoured,
unless otherwise stated, and this leaves a lovely handle, but this
somewhat limits the finished quality of knitwear you can make. True professionals will use greasy yarn and finish it themselves, but this usually means buying it on the cone.
