I always clean the thread and snippits of fabric off the floor every day that I sew. I have 2 kitties and I don't want them to swallow the thread. A friend of mine had a beautiful Himalayan cat that swallowed some thread and it wrapped around her intestines. The vet did surgery, but it was too late to save her. So I always run the swiffer over the hardwood floors and get all the threads off of the sewing cabinet. It only takes a few minutes and I want to protect my fur babies..
