For a project one month our guild made thread catchers to use at our sew-ins. The problem I had was the threads stuck to the inside the catcher. I took one of those large square plastic juice bottles, cut off the top and it fit perfectly inside the thread catcher, all my threads go in there, when I am done for the day, I remove the insert, dump it and no stray threads to clean up. When I leave my knitted pincushion fits inside the insert (my nipping scissors are held by my pincushion, as is Jack). Cleanup is fast and easy. My sewing room is so small and cluttered with fabric, there is no room to throw threads on the floor.
