I knew that I had some denim printed card somewhere and it has taken m days to find it. On the positive side, I have tidied up my stash on the way!
The sentiment is a die cut.( Tattered Lace)
Finally, I used a Martha Stewart punch to cut the single butterfly, glued it to the denim card and then cut round the shape. This has been added to the card with a 3D Foam pad.
