I have an idea for some yardage. At the moment it looks a bit like this.
It’s not an especially unusual idea, although it might entail some new challenges. An the idea doesn’t include anything about what the yardage is for, just that it could be brought to existence. However, it has got my fingers all itchy to be winding a warp and annoyingly I have to go down to London for a meeting at the crack of dawn tomorrow morning. (Somewhat earlier than dawn, actually; alas, the days are shortening fast.)
