The Coopers’ Guild is always busy. Many things that go aboard ships in Waterdeep’s busy port, notably pickled fish from the Fishmongers' Fellowship and the wares of the Vintners' Distillers' & Brewers Guild, require its barrels.
Members of this guild cut, steam, and shape the wood, and form and weld the metal bands of barrels themselves (from foot-long hand-keg, with rope handle, to 20-foot-long cellar cask).
