There is a lovely saying that is used on special occasions to help mark that someone special is not able to be there.
"Because someone we love is in heaven there's a little bit of heaven in our home" is the saying which is often used around the home and especially at Christmas time when it is a family occasion and everyone likes to be close to those friends and family that we love.
We have a lovely wooden heart shaped Christmas tree decoration that has this saying on and can be hung from your Christmas tree or can just be hung up all year around. You can buy our "Because someone we love is in heaven" bauble here.
For weddings this saying can be adapted slightly to read:
"Because someone we love is in heaven there's a little bit of heaven at our wedding".
You might again find that this is hung from somewhere or carried by the bride or groom somewhere on their wedding day if there is maybe parents or Grandparents or friends who have passed away. It just helps you remember them and have that feeling of them being there in spirit with you on the wedding day.
