I need to make up a fairly big notice board for work...probably 8 x 6 feet. It needs to be fairly permenant and strong enough to take a large cardboard wall planner among other things.
I was looking ar cork floor tiles glues to the wall but they only go to 4mm deep and im not sure that'll be deep enough to take a drawing pin !!!
I did this once in a classroom back in t' day when you were allowed to. Using the thinnest chipboard, screw to wall resting on skirting board. Paint with emulsion colour of choice.
Keep one eye out for the jobsworth who represents fire hazards as they will say 'you can't do that'.
