Keith,

I have been following your progress in this thread with interest, not because I intend following your example (I know that is WAY beyond me) but because I admire your talent. However, I am intrigued to understand the shaping of the yellow 'flashes'. Is there a particular reason for them to be shaped in that curved manner?

I know nothing about American sport, and very little about British sport, so no doubt I am missing something obvious to every sport-loving American, but perhaps you would kindly put me out of my misery!!
