I dyed one skein with 5 packs of Grape Flavor Kool-Aid:
|Original orange yarn on left/ re-dyed yarn on right|
I am not completely done with the cardigan yet... I ran out of yarn (had used 10 skeins) before I finished the second sleeve... So I just dyed another skein to finish up the last 12 rows of the sleeve.
Oh yes, before I forget, the cardigan is knit from the top-down with set in sleeves = completely seamless (not sewing!).
