Choosing the right organizing product can be overwhelming. It's often difficult to visualize the right product and know what size to buy. My advice: simplify and try not to over-think the situation. Do you really need to buy a product or do you have something on hand? Take measurements and visit your local organizing store. Ask the professionals who work there for help. They are often trained in determining the best solutions for the job. And remember, if it doesn't work when you get it home, you can return it.
