First, stamp on vellum with Versamark and emboss with your choice color of embossing powder. Here I used Pool Party. Then, turn the vellum over and color with Stampin' Write markers. I used Rich Razzleberry, Tempting Turquoise, Garden Green, Melon Mambo, and Daffodil Delight.
First, I filled an empty stamp case with paper towel and saturated with bleach. Then, I stamped the Swallowtail in the bleach directly on Basic Gray cardstock (Melon Mambo cardstock also looks great, but note, this does not work on Basic Black cardstock!). Then, I spritzed with black ink, added accents using the Chalk Marker, and finished off adding some rhinestones.
This card I CASE-d (copy and share everything) from Dawn Griffith. She stamped the Swallowtail on vellum using Black Stazon ink. Then, turn the vellum over and use a stylus to dry emboss the details. Then, two squares of Basic Gray cardstock were added behind to add a contrasting look. The vellum was adhered to Whisper White cardstock using silver mini brads.
