Whilst demonstrating as a member of a local textile group, Woolly Umbrella, at the Wild Chalk festival, I kept a drop-spindle of my own going with singles that I Andean plied at the end as part of the demo.

I don’t think repeatedly putting it down and restarting helped me get an even twist, or it may have been the plying, or a mixture of both, but the yarn isn’t balanced. I knitted a lace pattern with it, and the bias isn’t so pronounced as in stocking stitch, but I can see it.
For fun I added the knitted sample to a purple dye bath I had prepared to dye some other yarn, and here is the result.

Hand spun yarn dyed with purple acid dye.
