I had the opportunity to enter a contest recently. Literary Taxidermy seems interesting, in that they give you the opening and closing lines to a famous work and you work your story off of that.
I'm not really big on contests, but I looked at this one's different nature and decided, why not? Personally, any contest that doesn't charge a fee, I'm willing to look at. Unfortunately, I don't have much time left over after working all the projects I have.
However, take each contest on its merits and see what it has to offer. Literary Taxidermy has no entry fee and flash fiction is a challenge I like.
Hopefully, they will like my entry as mush as I liked writing it.
