I used what I couldn't call a hint, tip, hack (yuck!) or suggestion in the truest sense. But I remembered something that another Mumsnetter posted on a thread I was reading, and I was touched by it. She said that she put her late Mum's last birthday card to her up on display on her birthday after her Mum had died. How lovely ❤.
Today I've put my Mum's last Christmas cards to us up. She died in January this year so they were the last written thing I have from her and she was very fond of cards and occasions. It just feels nice - thank you fellow MNetter whoever you are!
