I use the the small plastic boxes with dividers to store needle packages. Easy to sort by brand, type, and size. Another plastic box holds sewing feet. Plastic fridge bins are the perfect size to store fat quarters. Mine are 16 inches long and fit right on the closet shelves.
Double -sided fishing tackle box holds the sewing notions by my machine. It's easy to pack up for sewing class.
I search out containers for their specific size according to storage needs. Buy multiples so they can be stacked. Remember to label contents in order to easily locate the items later.
Organizing can be fun!
