I used the trusty X-Cut Shape Cutter doodah for the 'porthole' and a lovely little pin (with guard, before you all shout at me!) stuck through the bow.
Found a sweet verse: "A child to enjoy is a gift from above, to be Christened and cherished and brought up with love", although my personal favourite (but then I do have mental issues!) is "First he's born, grown up and wed, gets a pension, then he's dead". Made me chortle a LOT, but apparently it's not that suitable for a Christening card. TFL xx
