I suspect that every spinner has made unloved yarn. Buy some roving, sight unseen. I believe this was called “Partridge” from Autumn House Farms. Then spin it up just to do that. I did this back when I first moved in with Lon and the house was full of people, when I was shy about spinning at a new place. Ply it just to clear off the bobbin for another project.
What you wind up with is unloved yarn. I have no idea what I will do with this. I will try and use my imagination just to see if it can be useful, even if unloved.
