Surely everyone has a drawer devoted to just 'junk' right? Well junky doesn't have to mean messy.
For all of those odds and ends, things that might be useful one day, finding an organised place to stash them means you can put your hands on them quickly and easily.
Sort what you need then get some drawer dividers. They come in various shapes and sizes so you can tailor them to suit a wide range of drawers and storage needs.
If you don't want to buy drawer dividers, you can still create order by using left-over boxes and containers that are shallow enough to fit neatly within the drawer.
