The floor in my sewing room is most often littered with lots of thread and little snippets of fabric. I don't know why the stuff doesn't make it to the waste basket.
I usually at least vacuum between projects.
My biggest problem is when I pull fabric out to "audition" it, I have a hard time forcing myself to refile it all back to it's proper place. That's why there's a big 3 foot pile of unsorted, unfolded fabric on the closet floor.
