The reason I like my flat side by side fridge and shallow wall pantry - things generally can’t get buried in the back behind other items.
@BunsenBurner - I agree! In the largest house we ever owned, we had this dreadful corner pantry - it was like a black hole!
I am apparently no longer good at following directions since I can’t bring myself to work in the kitchen today. ( I did go through the fridge, freezer and pantry within the past month, so they aren’t too out of shape.)
Instead, I just spent the morning pouring through 3 gigantic containers of Halloween decorations, costumes I made for the kids, and party games, props, and crafts that I made as a room mom for many years, times 3. Each costume brought back such memories! I sewed the costumes, some parts by hand, so I am not parting with those yet. But I am able to eliminate one of the containers of stuff by donating store bought costumes, masks, and other things.
I still decorate for Halloween so am keeping one container for fall/Halloween/Thanksgiving.
I am spending the whole time on the pantry. We just recently got a new counterdepth refrigerator and things do not hide anymore. We cleaned out when we moved things. But the pantry … that may be an excavation, We have deep cabinets above the washer and dryer and have a large corner shelf where the corners are hard for me to see. Who knows what lurks there 
I slacked off the last couple of days reporting in here. Sorry, wasn’t actually cleaning either! I still would like to “sweep” again in January. Here are the last couple days - and the end I think!
Day 14:
Today’s Assignment:
Make a plan for future purging.
You don’t have to select a specific day or time in the future to declutter, although it’s great if you want to. You can simply set a calendar appointment (“Declutter-palooza”) for a weekend in three or six months.
The important part of today’s assignment is setting up a system that makes it easier to decide what to let go of then—whether that’s in three months, or this time next year.
Here are some ideas:
The backwards hanger trick
Turn all the hangers in your closet around so the hooks are pointing towards you (aka the wrong way 'round). When you wear something, put it back with the hook the normal way. When you revisit your wardrobe, any hanger still facing the wrong way is holding an item you haven’t worn, ready for the donation bag.
The safety pin trick
For any clothes not on hangers, you can loop a safety pin around the tag or belt loops of all your folded clothes. When an item is worn, remove the safety pin. Similar to the hanger trick, when you go back through your clothes, anything with a safety pin still on it is ready for a new home.

Mark things with washi tape
In rooms like the kitchen and bathroom, you can mark your collections of tools and appliances with a small piece of washi or masking tape. Whenever you use something, peel the tape off. Later, any item still sporting its tape can be confidently discarded.
The box & banish
Maybe the easiest way to make really deep cuts is by prematurely boxing everything up right now. You can take a collection—like books or servingware or shoes—and dump the whole thing into a box. Cast that box off to a garage, guest room or under the bed. When you remember and need something from the box, go grab it and return it back into the fray of everyday life (aka the shelf, cabinet, or closet). When some time has passed, you can get rid of everything left in the box, guilt-free.
You can choose one of these strategies and apply it to your particular problem area (I hope that, amongst the actual decluttering, the September Sweep has also given you some clarity about your relationship to your things). Or do all of them and really get a grip on what you need and use every day, and what’s better off donated to a new home.
And don’t forget:
Clear three things from your monster zone. The final three things!
Day 15 - Last day!
Today’s Assignment:
It’s “deal with it” day. Collect your “wanderers,” “sell,” and “donate” boxes and deal with the stuff inside.
There is lots to do from here. You can and should take the weekend to handle it all. Make it so that the last thing you have to do on Monday is drop off the donation, mail the package, or post the listings.
First the wanderers:
The wanderers box we set up on day one was our temporary home for things that didn’t exactly have one. Item by item, pick up the things in your wanderers box and decide what you want to do with them. There are a few options:
I don’t want this anymore: Easy! Toss it out to the trash or recycling, or set it into your “sell” or “donate” boxes.
I still want this: Find a home for it. Easier said than done, I know. But answering these questions might help: Where will I be when I use this? Where will I look for this the next time I need it? How often will I use this?
I’m… I’m not sure: This one is the toughest spot to be in, to be sure. But you’ve been such an ace all month at deciding what to keep and what to toss, that you should proceed through your wanderers with clarity. Use the five questions if you need to. But ultimately, remember this: Did you miss it all month long? No? Feel good about saying goodbye.

The things you want to donate:
Your donation pile is likely a mixed bag of goodies. If you’re craving some instant gratification for getting these things out of the house, take the whole box to a place like Goodwill and let them sort it out.
If you have the energy to do a little sorting yourself, however, there are plenty of specialized charities that will take certain items off your hands and give them deserving new homes. Just check out 10 Charities That Will Give Your Old Things New Life.
The things you want to sell:
For all of the things that you know have some value and it’s worth your time to sell them, you have a few options.
If there’s not much in the box, or if a few things stand out to you, you can post individual listings on local sites like Craigslist, Apartment Therapy Marketplace, LetGo, or OfferUp to connect with individual buyers directly.
Local consignment and thrift stores are great for when you have a lot of one type of thing to sell. If you have a box of clothes in good shape, for instance, you can search online for a local consignment clothing boutique that might buy much of it off your hands, or sell it on your behalf.
Another great option, if you have a lot of clothes to sell, is ThredUp. You mail them a big bag of clothes (ThredUp’s “Clean Out Bag”) and they’ll sort and process what’s inside and provide you with cash or credit for items they want to accept. They say they accept 40 percent of items in the average Clean Out Bag, and reuse or recycle the rest.
That’s it for the September Sweep this year!
I just figured out how I want to repurpose the craft closet. I realized that doing so will give me a shoe closet in the main room where I get dressed. This is an exciting thought! It’s motivating me to get the craft closet down to one shelf!
Moving my crapola into the newly refaced kitchen! I an being very picky about what is being kept. It certainly helps that (a) I am not pressed for time and (ii) I can’t carry much at a time because I am recovering from a minor surgery. I am keeping Mr. out of this because he would just shove everything back into the empty drawers. 
@BunsenBurner – yea! I did sort of the same thing a few weeks ago. I had my dining table crammed with stuff that I had pulled out of cabinets and beyond. Told H to keep his paws off! Took a bit of time but much went by the wayside and I feel much lighter!
