I use one of those plastic scrubbies on a handle that are used to scour sinks or to scrub potatoes, to clean my cutting map. It picks up all kinds of debris.
Buy those 4 inch long toothpick-like skewers at the grocery, tape them to the short spindles on my wooden thread rack and now I can add the bobbin to the thread spool, keeping both together.
And those wonderful lint rollers are so great for cleaning up the floor around the machine and getting all the threads off my flannel sheet hung up to display blocks (can't remember what we call it....).
