Writers are given the liberty to explore their ideas over a series of pieces. These 'threads' are woven together thematically or stylistically, and deftly touch on the feelings, objects, memories and passions that pervade our days, crystallising them into psychological and artistic truth.
They aim to "feel at each thread" of the mingled webs of our lives, as Pope says in his An Essay on Man:
The Spider's touch, how exquisitely fine!
Feels at each thread, and lives along the line.
