My recommendation for knitting with 2 skeins of one colour
The yarns are hand dyed and colours from one batch may vary in colour intensity and finish. To avoid a big difference in colour from one skein to the other in the knitted piece, I recommend to knit both skeins alternately (change the balls after every 2nd row).
Colours that are permanently available in the range have their own names. Colours with a number are only available as long as stock lasts.
