Arts and crafts comprise a whole host of activities and hobbies that are related to making things with one's hands and skill. These can be sub-divided into handicrafts or "traditional crafts" (doing things the old way) and "the rest".

Most crafts require a combination of skill, speed, and patience, but they can also be learnt on a more basic level by virtually anyone. Many community centres and schools run evening or day classes and workshops offering to teach basic craft skills in a short period of time. Many of these crafts become extremely popular for brief periods of time (a few months, or a few years), spreading rapidly among the crafting population as everyone emulates the first examples, then their popularity wanes until a later resurgence.
