A cotton plant is something I'm not particularly familiar with but this image is SO pretty (and the flowers look very much like roses anyway!).
For this one print:-
The Cotton Plant large pyramage sheet onto quality white card
The Cotton Plant background onto quality white paper
To make the card:-
Cut out all the pyramage pieces as well as a greeting and a border strip using a craft knife and ruler.
Make up the pyramage stack with double-sided tape, silicone glue or sticky pads - I've done this one with double-sided tape so that the picture can be seen more clearly.
Cut a 4cm strip of the background paper and add it to the bottom of an ivory or white A5 card blank with double-sided tape.
Add the border strip and greeting with sticky pads.
Finally, add the pyramage stack with double-sided tape.
