Black Crow Sampler Threads by The Gentle Art 5-Yard Skein
Sampler Threads were the very first over-dyed threads I ever used, and I've been using them ever since (gosh, about 25 years now!) These are a six-ply floss (just like DMC), and they are hand-dyed and gently variegated. Threads can vary batch-to-batch, because of the nature of the dyeing. I think that's charming, but if you want to make sure you have enough of a dye lot for one project, make sure you get too many, rather than too few.
