I'll do another shot later with some colour added so you can see it in all its glory.
I'm tempted to extent the experiment until the number of people who have noticed it (who didn't know I was growing it for charity) has hit double figures - I fear this could take a while.
Thanks for your support. Whilst my tache is pathetic the cause isn't.
Edit: You'll probably want to click through to large size to see any sort of facial hair. WARNING - this will enhance the UGLY and display my morning ashen look in its full horror.
