Ok, food colouring is out because it's too permanent....but how about good old Kool Aid? No harm in that, is there? I want Sammy to be black and orange for Hallowe'en. And I'll be able to wash it out after a few days, right? I'm looking to do this in time for the Trick-or-Treaters, so if you have anything to say on the subject, now's the time!
