The 'Core 4' Method: The Decluttering Approach Professional Organizers Rely On

An organized environment can significantly improve our daily lives. It simplifies locating things we need, creates a sense of calm, and even helps save money over time since we are less likely to lose or forget about items when our possessions are properly arranged. However, maintaining that order can feel daunting. Committing to a specific method—such as the Core 4 organizing strategy—can help you stay organized with ease.

What exactly is the Core 4 Organizing Method?

The Core 4 Organizing Method, developed by professional organizer Kayleen Kelly, simplifies the overwhelming task of decluttering and organizing into four straightforward steps: Clear Out, Categorize, Cut Out, and Contain. This method is highly recommended by countless professionals and is used in their everyday practice—and it’s a strategy you can implement in your own home too.

“Whether you’re organizing a single drawer, an entire room, or any other space, the Core 4 method will empower you to accomplish your goal,” explains Wendy Trunz, head organizer and partner at Jane’s Addiction Organization in New York. “Once you have all the right tools, you’re ready to get started.”

Here’s what you’ll need:

• Trash bags
• Post-it notes/labels
• Markers
• Bins or boxes of different sizes
• Tissue paper and/or bubble wrap for fragile items

Once you have your supplies ready, simply follow these four steps to get started.

1. Clear Out

The first step in the Core 4 organizing method is to completely clear out the area you want to organize. “We recommend removing everything,” says Ashley Stewart, professional organizer and owner of Organize. Create. Design. in Phoenix, Arizona. “Whether it’s your garage, closet, or pantry—take it all out!” It may feel chaotic at first, but think of this stage as the storm before the calm.

2. Categorize

After clearing everything out, begin sorting items into piles of similar things. You can also use bins, boxes, or containers to help organize. “Label each pile with Post-it notes as you go,” suggests Trunz. “It keeps you on track, especially if you need to take breaks or have others assisting you.”

For instance, you can place photo albums and framed pictures in large bins, while using smaller bins for loose photos. If you're working in the pantry, you could group baking items together or set aside a separate pile for pastas.

3. Cut Out

While sorting through your items, be sure to remove things that you no longer need or want to keep. Keep large trash bags for discarding waste, a box or bag for donations, and another for items you may want to sell (if relevant).

Trunz recommends asking these three questions during the process:

• Do you want to keep it?
• Do you want to sell it?
• Would you like to donate it?

“This approach helps people let go of things, knowing that what they no longer need could truly benefit someone else,” Trunz says. It may even help generate some extra cash if you decide to sell your items.

4. Contain

The final step is to use bins and containers to store your grouped items. “We love using baskets and clear bins for organization,” says Stewart. “When like items are stored together, it’s much easier to locate what you need and also simple to return things to their proper place.”

Clear bins offer the added benefit of allowing you to see what’s inside, making it easy to find what you need when the time comes. Regardless, both organizing experts we consulted agree: labeling everything is crucial. It also makes it easier to add future items that belong in the same bin or container.
