Grandparents LOVE personalised plaques from their grandchildren, (don't tell but I was made a Grandma a few years back & now blessed with 3 grandsons!) Never be stuck for a gift again.
Our grandparent tree's are extremely popular where you can have your parents names on the main plaque so maybe you would have 'Nana's House'
where memories are made You can buy the wooden hearts on their own too perfect to add when a new grandchild is born.
They are presented in a small organza bag & so easy to pop in the post
I have more grandparent plaques here 'Grandparent Gifts'
