I got christening candles made, one big one for the baptism, and two little ones for each godparent, with a special message to each one from Charlie thanking them for agreeing to be a part of his life.

The person I got it from will even put your baby's photo on the candle if you want, so it's more personal. His godparents were very touched by it, and his godfather has it in pride of place in his display cabinet.
