The name sake of each new colorway is from Classic Greek or Roman Mythology or simple words or phrases. To find the meaning you can do a simple word search on the internet using a greek or or latin dictionary. Of course, you could always knit or weave along in blissful ignorance of the colorway's name, but where is the fun in that!?!
And we are now dating our yarn so that dye lots can be more easily identified! For example: 4/11 means the yarn was dyed on April of 2011. Yarns dyed prior to 4/11 will not be dated. Although the date might be the same, I would like to remind you that hand dyed yarn can vary greatly from skein to skein. Needless to say, if you have a large project in mind for the yarn, I recommend alternating the skeins every other row;)
