The art of bowing.

[David Powell]

OK, so this is one of those "how close" is close to the bridge and "how close" is close to the fingerboard questions? I've put it on the calendar (the only way I can stay on track) to get that book, Ken, and I certainly appreciate a helpful passed on tutorial, but just how close is close? Is this like horseshoes (closer than the rest) or calculus (approaches but never gets there);- how close is as close as possible (calculus?) and how close is as close as comfortable (college roommates)? Reasonable estimates accepted in fractions of distance between FB and bridge, inches, or centimeters .....
