Putting a bit more twist on the 2 ply spindle spun yarn did the trick. It still hung straight the way a balanced plied yarn should. I rewashed it and hung it to dry. The balance stayed put. Onward with my plan! Originally, I wanted to knit Mim's Persephone with it. The cashmere and silk are very soft. Perfect scarf yarn. My sister (you know Linda) agreed to knit Persephone, as it is offered in the kit, with my Arbori so that I could go ahead with my original plan. I'm using the Arbori yarn in the same Purple Haze colorway for my Muir shawl. The handspun and the Purple Haze are fairly similar in color and intensity. I didn't need three projects on the needles in the same colors.
Persephone is a very enjoyable knit. I do need to pay attention. Not so much that I can't watch a movie and knit, but I need to keep the chart close and refer to it each line. ONe repeat down.
