This idea is so brilliant, perfect, and touching, it gave me tears. Astrid of Red Red Completely Red says,
When Tilly was born, my grandmother, Mormor, gave us a tree. We picked out an oak and planted it in the garden in March. Today, we hung the tree with hearts. In each heart is a little message to Mormor, who sadly passed away earlier this week. And though our own hearts are very full of sadness, we feel very grateful for the love and the memories that will live on.
Thanks for sharing this. Being so far from family, it helped us to feel like we were honouring her in our own way.
