Iimagine most decorators will be interested in the brushes and solvents thatother decorators use, and where they get them, and on what terms, and I expect they’ll be just as interested in each other’s methods and how they get the best use out of those solvents and brushes. They may even be curious about each other’s lives, how they organise their weekends, and if they pay into a pension plan, and whether they know a good osteopath. And no doubt the same will go for plumbers, photographers, ceramicists, chefs . . .
