One problem with changing tables is that the drawers are huge and the child's clothes are about the size of my socks. The drawers are not sectioned out at all. So I decided to make my own sections. This is my solution and process.
Step 1: Define Sections
I needed to figure out how many sections I wanted and how big I wanted them to be. The drawer is 32" wide, I put a 4" section for socks and other small articles of clothing and 4 sections at 7" each.
I measured out the length (12 3/4" for me) of each board.
I had a nice piece of wood from a bed-frame that I had found in a dumpster. This board was 6" long and so it was going to work great for 5 dividers.
