I invented something before breakfast! (A new kind of reed for use in rigid heddle looms.) The invention was prompted by an article in WeaveZine by Syne Mitchell (who once sold me stories when I worked as editor for a fiction magazine).
Of course, once I started trying to record the original idea, seven variations popped into my head, so breakfast was very late indeed as the ideas took precedence, clamoring to be recorded and illustrated. -- Rachel Holmen
