I submitted two entries, and the first one (October Moonlight) was extremely difficult to scale back. I felt like I needed every word to contribute to the mood and setting, since it was a dream sequence. I would write some of the story, then check word count, then scale back then continue writing, check and prune again. By the time I had finished, I was still at over 600 words, and it about KILLED me to have to cut and cut my descriptions, for I felt it kept altering the intensity of the original story I had set out to portray.
The second entry was a poem (Kink before Christmas), and I will honestly admit that it pretty much wrote itself from start to finish. I paid no attention at all to the word count--just set out to tell the story and when all was said and done, it was almost exactly at 500 words. Thank goodness, because having to cut back words in a poem affects the rhythm and meter of the lines, so I would have had to eliminate a complete stanza to bring it within the limits. Fortunately, it all fell into place!

Overall, it was an enjoyable challenge, as I had never written something in so few words before. It really makes you consider word choice and decide what is truly essential in developing a meaningful plotline.
