There are forgotten rules I have had to remember…..Hands clean and dry at all times….No coffee, food or cigarettes on worktop.…If windows are open and a tiny flying bug lands on drawing blow it away – a swipe with the hand can result in bug-blood on the sheet!....Desk as uncluttered as possible….Always try a pen on a rough piece of paper first to be sure it isn’t bleeding or acting funny….Use a couple of clean sheets of paper to avoid hand/elbow contact with drawing sheet as much as possible.…Allow a minute to use eraser after working with ink to allow ink to dry and avoid disasters.
It’s all slowly coming back I think.
Up to now I’ve got by without serious injury.
