I had seen this technique a long time ago on StampTV and never gave it a try until earlier this year. I didn’t post it until now probably because I forgot to it but when searching other photos I found it again.
On Black CS I stamped the butterfly all over with VersaMark and then heat set them with white embossing powder.
Then I hand coloured all of them with different pencils to get this effect. I used a tiny word die here and there to finish the card.
