Simple "arts and crafts" projects are a common elementary and middle school activity in both mainstream and alternative education systems around the world with the aim to develop children's and teens' practical skills, such as everyday problem-solving ability, tool use, and understanding of the materials that surround us for economical, cultural and environmental purposes.
There are almost as many variations on the theme of handicrafts as there are crafters with time on their hands, but they can be broken down into a number of categories:
Using textiles or leather;
Using wood, metal, clay, bone, horn, glass, or stone;
Using paper or canvas;
Using plants other than wood;
and Others such as: Balloon animals, Cake decorating, Egg decorating
