You can! But consider that store-bought organizers come in standard sizes that force you to “make it fit” in your closet. And most of those shelves are low quality materials. Lastly, it can be a big job with no guarantee. We have many customers who tell us the reason they want our help is because they tried to do it themselves and were unhappy with the result. Reunity takes the headache away, and we have a lifetime guarantee on our custom closet solutions.
