I have spun and wound off one spindle full, and started another one. I spin wool samples, which is very fun. I don't get bored because the colors and the qualities change so often. I have planned a fourply cable, but it might become a threeply as well.
I have spun one bobbin on wheel, but I only have a picture of the sample card so far. It's "sewing thread" with a 3-ply ply-back.
