bequeathing personal possessions

Now well into my 80s I'm beginning to think about the personal possessions I'll bequeath to my 3 children.
Financially there should be a small amount for each of them, but I'm quite attached to my few personal things and would like them to by shared fairly.
Some paintings, old photos and letters, newspaper cuttings, jewellery (not valuable) etc.
Have others faced these decisions - what did you do?
