Secondly an anglepoise lamp with a desk clamp and an old grey ant-static mat (obtained from my workplace who were having a throw out - waste not want not). The desk and cutting mats I use had a thorough clean, its amazing how much gunge and dusty bits accumulate over a year+. I put the grey ant-static mat down as a workbench protector and put everything back; with the anglepoise clamped to the back shelf I have now got more room on the desk.
I've yet to put back the paints and work in progress, but its clean - at least for while :-). Next job is to tidy-up the sourrounding shelf.
