There is nothing like the joy of a full bobbin. It is something beyond the sense of accomplishment or the possibilities of finished objects to come. You KNOW that fiber. Every bit of it has passed through your fingers. You have put some of yourself into it, and thus it is a part of you. You have transformed it from one stage of its being to another, and knowing it so intimately, you see the beauty of its simplicity and form. I imagine woodcarvers and potters and other folks who make things with their hands feel similarly about their process and product. How does one distinguish an artisan from an artist? In my mind (as of this afternoon, anyway) an artist is all about the completed idea, while an artisan is about the interaction with the materials and the skill of the execution, in addition to the beauty and usefulness of the finished object. This is why I prefer to be an artisan rather than an artist.
Apparently a full bobbin inspires philosophizing, too.
