I've seen similar cards on Pinterest (usually with Washi tape and one feather). I'm not big on Washi tape, so I decided to use several feathers and stamped them on vellum. The background is stamped first with a stamp from "You've Got This" and then with the splatter from "Gorgeous Grunge." All stamping was done by stamping off first so that the colors were light and not saturated.
I sponged the edges of the bird, the leaves and the background with Sahara Sand. When assembling the main image I added a feather charm I had from jewelry making. Finally, I used the RV99 Copic marker to color the rhinestones Blackberry.
