Here's what we came up with:
- slubby cotton wrapped around a core
- mohair boucle
- silver lurex bullion
. . . no that's not three yarns: all those techniques went into the one. We worked in pairs for this exercise. M and I chose white/neutrals and with a silver touch. M and M, the other team, worked in strong pinks and greens. With exactly the same basic structure, the effect was very different. I'd like to repeat the exercise on a few more commercial yarns and see what I can learn. On the other hand, spinning by hand does have some different constraints . . . and all those special techniques are intensely time consuming. Still, it's always good to extend and learn some more.
