Our grandmother loved butterflies. They were her trademark; butterfly stickers on our birthday card envelopes and butterflies on the place-cards she used at big family functions so we'd all know where to sit.
You might already know this, but it's tradition to place a stone on a jewish grave, as it indicates longevity and doesn't wither, as flowers do. My sister Kate had the idea to give each of the great grand-children a white tile for them to paint a butterfly on to leave on the grave. Z was going to be at his mum's on the day of the painting, so he drew it a few days earlier and Kate copied it onto a tile. Kate, you did such a great job!And so did your girls. Booba would would have loved them.
