HappyNan1 I do that... take photos of once-precious items and clothes of sentimental value, then give the things to the charity shop and it works brilliantly for me. I've been doing it for several months and the photos are all in my phone and I find I'm now really rather enjoying seeing this stuff, often unexpectedly, when I'm flicking through my pics, rather than having 'redundant' objects in the house and wondering what on earth to do with them!
It all started for me with a Victorian chamber pot which was presented to me in the pub when I was a student, on my 21st birthday... full of foaming beer! Everybody there had to have a mouthful and pass it on. (We knew how to enjoy ourselves in those days...) My friends assured me the pot had been thoroughly boiled
. In the course of the next 40-odd years it had been an 'ornament', a plant pot, a soap container etc, but, although it was of sentimental value, a few months ago I decided it was time for it to go to a new home. It wasn't very attractive (not one of those decorated with colourful bouquets!), and none of my children wanted it so I took a photograph of it then took it to the charity shop before I could change my mind. I smile and remember how I came by it every time I see the pic and I feel glad that it probably raised a little cash for Cancer Research as well as giving its new owner some pleasure... or maybe they even use it for its proper purpose
.
I'm in the middle of a huge decluttering effort which is proving very hard work as I am a reformed hoarder, but I'm very excited at the prospect of not being surrounded by things which have no future, either in my soon-to-be decluttered home or with my family. Eventually I plan to get all the photos printed and have an album of my ex-treasures!
Davism01 I quite understand how you feel about your mum's things. My mum died last year. She was a lovely lady, much loved and I have many of her and my father's possessions now in my house and I find it much harder letting their things go than my own. I intend to keep certain special items, but others that are not wanted by family members will be photographed and taken to the charity shop. I feel that way I will enjoy the memory of the items and the fact that my parents' possessions are being appreciated by their new owner as well as helping a good cause. I feel sure my parents would give full approval to this solution. Whatever you decide to do, Davism01, I wish you luck, it is so difficult. 
Sorry, I have rambled on a bit, but this is a subject close to my heart at the moment!
