I do have a thread catcher "bag" that hangs from my sewing machine, so many of the threads do collect in there. On my floor I have hardwood floor, and I keep a swiffer in my sewing room closet, and you would be shocked at how much fluff and threads, that swiffer has on it when I'm done swiffering up my sewing room. And that's after I've tried to put all the threads in the thread catcher or the trash. I have never thought of doing something with the threads..........could one stuff a pin cushion, or something??
