Oh my what a job. I am in the process of cleaning out my things too so my room is a mess but I am going to send pictures.
I found out that the plastic drawers can be taken apart and rearranged to fit what you need. $11 at Family Dollar,
the baskets in the closet, $4 at Big Lots , there is a bunch more, are organized by color, or type , flannel in one and holiday in another and the shelves hold my books and ironing things.
I don't know if it will help any but maybe it will give you some ideas for things you already have.
