I also use the bobbinsavers for bobbins. I use various containers for different quilting needs; compartmented box for sewing machine feet, file type box for patterns, small boxes for different type pins, another box for templates. Recently found two thimble shaped ceramic containers that I stand small rulers, marking pencils etc. in. Use canning jars for buttons.
And, I have an old Princess sewing basket for general sewing. Also use a large gardening bag to store my square rulers, small cutting mats, specialty rulers and the outside pockets for various notions.
