There was an old Nelly song back in the day (i'm so old) and the whole song and video was all about shaking your tail-feather (and obviously, many close-to-naked women obliged.)
Just in case you were wondering about the background of my card... inspiration is a funny thing sometimes!
I used lawn fawn's "quinn's abcs" for the letters (and had a mask a few for them to fit the right way....) The feather, from "lovestruck," was stamped once near the "it's your birthday" sentiment, and then without re-inking, stamped a few more times so it looks like the feather was floating down... you know, a stray plume came loose from one of those floozy video girls costumes... hee hee. I stamped another feather onto a separate sheet of white cardstock, and colored & cut it out.
I also added a bit of shimmer to the bottom:
I adhered a strip of double-sided tape, and dumped glitter on top. Instant bling.
