Well, before I got my last disappointing Craftsy purchase I had already ordered these as well. I was worried I would have the same problem - that my dye lots would be different. I am thrilled to report i had no such problem!
All of my skeins were from the same dye lots! Yahoo! So, it seems to just be luck of the draw. Sometimes you win, somethings you lose. But at least it restored my faith a little :)
