School subjects that aid a quilter
When you were in school did you take a course in something not knowing what on earth you'd use it for, but found out later that it aided you in quilting?
One such subject I can think of is Geometry. At the time I didn't have a clue as to what I could do with that knowledge, but since taking up quilting, I found I had a fairly good understanding of angles and measurements, thanks to the geometry class I had in school.
Are there any other classes you can think of that helped you personally in quilting?
