I buy several plastic pencil boxes each year. I have to secure all my machine accessories because I have two very nosy cats so I use the pencil boxes for my sewing machine feet, bobbins, and other accessories. Each machine has one or two and they are labeled so you know which boxes go with which machine. I also keep an assortment of seam rippers, stillettos, screw drivers, and brushes in one of these boxes so it's handy while I'm sewing.
