Knights and nobles weren't the only ones who used coats-of-arms. Medieval Guilds would often display a coat-of-arms in their guild hall. A guild was a group of skilled craftsmen who did the same job. So, a group of shoemakers living in the same town would have formed a guild to make sure shoes were made to a certain standard of quality, to make sure that they sold for a fair price, and to make sure that their members had specific skills. To become a guildsman, a person had to go through three steps: apprentice, journeyman, and finally, a master. The two shields above represent the blacksmith guild and the shoemaker guild.
