Glut of stories

I don't know how it happened, but I seem to have a large number of stories almost ready to be reviewed in a workshop. I'm taking an eight-week class which expects a story a week, and I seem to have a few extra. Now all I need is the guts to send a story out.
I have notices my writing is getting shorter. After talking about it with a friend, I realize that I'm experimenting, especially for this class, and I'm not experimenting on a grand scale, but I'm doing the equivalent of thumbnail sketches. I will probably get back to my longer prose voice as these experiments continue.
