This is optional but highly recommended; if your house was built before 1978, chances are there are several layers of paint. To ensure you are testing all layers for lead, you'll need to scrape a small amount down to the base layer (plaster, drywall, brick, wood, etc.)
Having an organized closet has always been a must for me. I love a minimalist lifestyle. Everything is organized, easy to find, and I don't have anything I don't really need or want.
