Hmm...then at this point, I think a good thing for Scissors would be to start working on ideas for what you would consider an ending. Slice of life stories can go on for a pretty long time before they can come to a resolution, so determining the ending (or an ending) can probably pull you out of that. Sometimes you don't have to have all the little things worked out in the middle.
As for the other stories, I'm not quite sure what I can add to them.
