I love her method. The secret is not to take everything in its literal sense.
One of her good rules is to have the same thing in the same place. I found 9 bottles of cough medicine scattered around the house when I started. Now I know exactly where everything is. Whether it is first aid, scissors, pens, cottons, cleaning material, everything has its own place/
She does say don’t buy storage materials , but I found having lots of boxes really helped me organise. I have some big boxes in my under stairs cupboards. I have separate ones for baking dishes, Pirex. dishes, Pirex lids, cake making stuff. It males life so much easier just to look through a box rather than search the whole cupboard for a tin.
You really don’t have to throw out things you love. For clothes, I started with, things that don’t fit, things that are uncomfortable to wear, then clothes that I had not worn for ages. I have saved loads of money, as I only buy stuff I need now.
A lot of her ideas, like thanking clothes for their service is nuts. However my hoarder husband, who had paperwork going back 40 years, 20 pairs of shoes and loads of suits, suddenly took it on himself to have a clear out. He had 10 times the stuff to get rid off than me. I really could not believe that just watching me Marie Kondo the house inspired him, where 40 years of nagging had left him unmoved.
