A few posts back, a fiber day, I pictured my experiments of dyeing merino wool a golden shade. My last spinning project was to take 2 ounces of each of those shades to spin separately and then ply together. I ended with one 100yd skein that really shows the differences in shading and a second 60yd skein that combines the lighter parts of the darker top with the more yellowish gold.

Yarn, 60yds on nitty-noddy and 100yds in skein.
And a different spinner might end with completely different results. That is part of the fun of spinning dyed roving or top.
