Decide where you want the shapes to be on the card and use the template to create the design or draw the shapes on a separate piece of card so you can add them later by using 3D sticky foam for a raised effect.
Decorate the eggs shapes with ProMarkers, watercolours, coloured pencils etc. If you use ProMarkers as I did then bear in mind that the colours can come through onto the other side of the card so it is better to colour and decorate the shapes on separate card and then attach them to your card blank. Also, I've found some colours don't scan well so watercolour might work better.
