I really, really want to have a bash at this (http://www.artisthideout.com/introducing-fumage-i-didnt-inhale/), but given my charming/alarming clumsiness, it is quite possible that i will end up setting fire to something (and not even end up with any pretty pictures at the end of it). Has anyone here got any experience with it and can pass on tips so that I don't burn the house down?
