Below is my own tweaking of the Pixie Dust tutorial:
I emitted the particles from a plane I shaped very roughly like a piece of cloth, it wasn't until I got it into After Effects that I realised it looks much better with just the particles. After this realisation I decided that next I'll use a smaller object to sweep across the screen so that the particles' tail fans out nicely.
I'm really looking forward to seeing what I can do next, so far particles are very exciting! :D
