In all towns, the organization of craft associations spread rapidly downwards through the trades. These associations sought self-government. Craft guilds were gaining much power relative to the old merchant guilds in governing the towns. The greater crafts such as the fishmongers, skinners, and the corders (made rope, canvas, and pitch) organized and ultimately were recognized by town authorities as self-governing craft guilds. The building trade guilds such as the tilers, carpenters, masons, and joiners, became important. Masons were still itinerant, going to sites of churches, public buildings, or commanded by the king to work on castles. The guild was not necessarily associated with a specific product. For instance, a saddle and bridle were the result of work of four crafts: joiner (woodworker), painter, saddler (leather), and lorimer (metal trappings). In London in 1392 craft guilds included: baker, fishmonger (cut up and sold fish), fruitier, brewer, butcher, bird dealer, cook, apothecary (sold potions he had ground up), cutler (made knives and spoons), barber, tailor, shoemaker, glover (made gloves), skinner (sold furs), girdler (made girdles of cloth to wear around one's waist), pouchmaker, armorer, sheathmaker, weaver, fuller, painter, carpenter, joiner (woodworker who finished interior woodwork such as doors and made furniture), tiler, mason (cut stone for buildings), smith (made metal tools for stonemasons and builders), tallow chandler (made candles and sometimes soap from the fat and grease the housewife supplied), wax chandler (made candles), stirrup maker, spurrier (made spurs), and hosteler (innkeeper). However, the merchant guilds of the goldsmiths, vintners (sold wine), mercers (sold cloth), grocers, and drapers (finished and sold English cloth) were still strong. It was a long custom in London that freemen in one company could practice the trade of another company. There were paint mills and saw mills replacing human labor. There were apothecary shops and women surgeons. Women who earned their own living by spinning were called "spinsters". Some prices in London were: a hen pastry 5d., a capon pastry 8d., a roast pheasant 13d., a roast heron 18d., roast goose 7d., a hen 4d., a capon 6d., three roast thrushes 2d., ten larks 3d., ten finches 1d, and ten cooked eggs 1d.
