So here is my brief and over simplified way of organizing.
1. Decide what you want your space to be. Is it a linen closet, coat closet, etc? This cabinet had everything from dishes to fabric.
2. De-junk. One of the greatest things I've ever learned is, "You cant organize clutter" so get rid of it! I do this by pulling things out one at a time making piles. Keep. Give Away. Trash.
If the thought of doing it all is to overwhelming do it in stages. Like in this cabinets case, I did one shelf at a time over the course of a few days.
3. After putting away your piles to their various locations it time to put back what you do want in your space, organized! I needed this cabinet to be my craft space. So only craft/sewing supplies are welcome here.
I even added the hardware on the drawers that have been sitting in my basement for a couple of months.
Don't forget to think outside the box as far as storage containers are concerned. My tall containers are cereal containers from the kitchen section at Walmart. I still need to buy a paper tray organizer but that will come soon enough.
I love my new craft space, it is so easy to find what I need and so easy to clean up when I'm done!
