The second experiment. I took one remaining third of a half and attenuated it lengthwise.
Then I divided the long strip into 6 about equal pieces and spun those pieces with short draw on a spindle.
Here are the results, from left to right: singles, 2-ply, and 3-ply. This time I saw that the colours were a lot more blended already when I was spinning. The swatches will show exactly how blended the colours will end up being.
