To compensate, I alternate between the skeins every two rows so the differences cannot be seen in the finished object. Other skeins of this colorway which were purchased later are reasonably close and could be used in a single garment when alternated in this manner. Whiskey Sour sweater. I had purchased MadelineTosh DK in the William Morris colorway for this sweater about a year before I started the sweater. When I came back to the pattern, the amount of yarn required had changed (yikes!). So, I took a chance and purchased enough skeins to alternate with my original purchase. Luckily the color of the second purchase could easily be alternated with the first purchase.
