Just browsing Kat's list of flash fiction competitions and conscious that we have not set a theme for the Watling Street Writers weekly meeting homework for a week or so....

This leads me to a suggestion for this week/next week.

The Dirty Dozen is a 12 word micro fiction contest run by the online flash fiction magazine Vestal Review.

Entries need to be "somewhat risqué, but not X-rated."

The competition rules for entry can be found here along with some examples of previous winners.
Note that you will be directed to their submission manager to upload.

Prizes aren't huge but it could be a bit of fun!
