Don't you hate it when you go to a class, with a full plastic case of bobbins, and a box of pins...and you proceed to drop the bobbin case and bobbins are rolling all over the floor in every direction, unwinding as they go, and while trying to pick up bobbins you tip over the box of pins and the lid comes off and they all spill out, and you didn't bring your magnet to class? You are definitely the center of unwanted attention. Ask me how I know.
