Yarn is sold by weight or by length, but these days I prefer to think of skeins in terms of minutes of time invested. Each yard of finished, 2-ply yarn took me 2.1 minutes to spin (including spinning both singles and plying them together).
I managed to spin 1515 yards of yarn for the show, even with my broken finger. That basket of yarn represents 53 hours of work.
I guess that explains why weeds are taking over my garden and the dog is feeling a little unloved.
