The Third Word run a twice monthly flash fiction competition. It's free to enter, they only want 80 words and you can send multiple entries. There's a £20 prize each fortnight, plus the chance of publication.
It's hard to illustrate a competition where you can write about whatever you like, so here's a photo of something I like. I'll be extremly impressed if you work it into your winning story.
How do you feel about such tight words counts? Do they encourage you to have a go, or put you off?
