Marie Kondo says specifically not to declutter by room, or drawer, or cupboard.
Instead, do it by category of item.
e.g. coats and jackets - there may be some in a wardrobe, some hung by the front door, one by the back door, one in the other wardrobe, etc.
Gather them all up into one place, e.g. put them all on a bed. Then choose which ones to keep.
Put the rest into piles for A) black bin B) recycle bin C) charity D) sell.
Put the piles in the relevant place (correct bin, or bag up to take out of the house).
Then put away / put back the coats you are keeping.
But beware of the 'sell' pile. Do you really need the money? Is the item genuinely valuable? Is it worth your time to faff about selling it? Would it be better to just chuck it in the charity shop pile?
Then make sure the charity pile gets dealt with - put it in a bag by the front door or in your car.
Other categories might be all your cooking utensils, all your plates, all your bits of stationery (pens, blank paper, hole punchers, staplers), all your electrical leads and unused electrical equipment, all your jewellery, all your face creams, all your make-up, all your handbags, all your luggage bags & suitcases, etc.
Categories should be small. "Books" can be a too-big category for many people, so gather up all your novels (break it down into read and unread if you need to), then another day do cookery books, or reference books, history books, hobby books, children's books, etc.
'Kitchen stuff' is too big a category, so do pans one day, oven dishes another, cutlery another, etc.
