I’ve been seeing this technique all over the internet, especially using the Blossom punch. You can’t tell from the picture, but the flower is actually the negative part of the punch. I popped up the DSP so IRL there is a gap there.
And this is the card I made using the punched out piece of the Blossom. I also used the Modern Label punch to layer inside the flower.
The tone on tone coloring made it super easy to coordinate these cards.
