This lovely Art Nouveau stained-glass window cross works really well as an Easter card because of its pretty yellow and green colours.  

For this one print:-

The Art Nouveau cross sheet onto quality white card

To make the card:-

Cut out the small cross motif from the sheet as well as a greeting and stick both items to larger pieces of silver metallic card with double-sided tape.  Cut round with a craft knife and ruler to leave a small border.  Further mount the pieces onto ivory card and again cut around to leave a small border.   

Stick the items to an ivory A6 card blank with double-sided tape.
