Sorry to hear of your sad loss bernie, just put something personal about your dad, something that means something to you and your mum, don't rush into it,just sit down and have a think about the things you did and loved as a family, it is such a personal thing, when my mum went we just put something very simple, I can't remember the exact words but it was something like, " We feel you when the sun shines, we see you in the stars, you are forever in our hearts" it just seemed apt for her, hope you can think of something, take care bernie, we only have one mum & dad.
