Static cling when you try to but sewing threads in trash can while sewing. I usually have paper towels in my sewing area and soda bottle with water in case I want iron an fabric. I found that if I take a couple paper towels and wade them up in my trash can and pour some water on them that the next time I go to put threads in the trash can the static is under control This is what I have been doing anyway. Others may have a better idea
