I actually made 12 of these for a swap. I started with Shimmery White cardstock, and embossed the Swallowtail image on with my "Black Ice" mixture (black embossing powder and Iridescent Ice embossing powder mixed together - 1 container of each).
Then I colored in the butterfly using an Aqua Painter. I put some water in an old brad storage container, and added about 5 or so drops of reinker. Painted it on and let it dry overnight.
