This couldn't be much more simple.
Yesterday, Kim from Cuddly Buddly, asked me to make a sample card with this corner flourish, which she had just designed.
I printed it onto some CB paper, mounted the paper on black then yellow. Stamped a sentiment, which I cut and mounted with Nesties, then punched out a couple of butterflies with a Tonic Studios punch. I drew the outline of the butterfly from the diecut wastage onto yellow, cut it out and mounted it behind the black punchies, so that it would show through the holes.
Sure was simple!
