What should I put in ‘short description’?

A short introduction should be a very short introduction to your work. 

A short introduction is capped at 280 characters, which is the size of a tweet. This means that organisers and judges can have an immediate understanding of what they are looking at, which is good for when there are hundreds of applicants. They may also be used for social media.

This may feel like repeated information from the works description, but descriptions are not capped, and give you more space to define your work.
