This lovely Art Nouveau stained-glass window card is beautifully elegant.  This one's the 'crafter's' version (more cutting, takes longer) but see also the 'cheat-sheet' version! 

For this one print:-

The Art Nouveau Roses 7 sheet onto quality white card
The corresponding background onto quality white paper or card
The envelope sheet onto quality white paper 

To make the card:-

Cut out the 13cm tall motif from the sheet without the black border and stick it to a larger piece of card with double-sided tape before trimming round with a craft knife and ruler to leave a small border. Repeat with another larger piece of card to create a stepped effect.

Cut out an 8cm wide piece of the background paper and mount this to a larger piece of card in the same way as the motif, this time leaving a border top and bottom only.

Stick both pieces to an 80mm x 197mm card blank (the old Craft Tonic 'Small Tall' size) with double-sided tape.

Decorate with a greeting and some small (3mm) clear gems.

Make up the envelope as per the instructions on the sheet.
