Each skein of yarn is hand-dyed in my dye studio by me (Babs) or one of my three assistant dyers. As a result of the hand-dyeing process, each skein will be slightly different even if they laid next to each other on the dye table. However, they will be closest to each other if dyed all at the same time. I recommend that you buy all that you need for a project at the same time.
When using hand-dyed yarns in a project that requires more than one skein, we strongly recommend alternating skeins every other row of knitting to even out any differences.
