Once I had my cabinet painted I began to start playing around with the arrangement of my items inside of it.
With this arrangement, I grouped the items into categories. For example I grouped together; All of the medical items, all the hair, the make-up, body products, face products etc.
I grouped them as an initial starting point as I thought that seemed the most obvious arrangement to do due to the nature of each product.
I feel this worked well as it was clear to see the similar kinds of products were with each other creating system and consistency in the cabinet.
