Alrighty. To begin you need a base, obviously. I got mine from a picture from Anna Nalick at myspace.com. (www.myspace.com/annanalick) Resize, crop, sharpen. Do whatever you need to do to make sure your base is clean looking and the details you want to stand out are clear.
Create a new layer (Ctrl+Shift+N) and fill it with #FFACE4:
set it to Soft Light at around 63% opacity. The higher your saturation is, the more "pink" it will seem. The lower, the less.
so this is where you're at:
next, create a new layer and fill this one with #DBC1DD:
I chose to set it to Color Burn at 100% opacity. It's the same rule for this step: the higher your saturation the deeper the overall color and more "purple" it will seem.
k, so now you're here:
At this point you can use whatever brushes you want. You could add borders, patterns, textures, other images, WTFEVER YOU WANT. I just used some brushes from The Magic Box in the color #7C5274. A tip is that when you're going to combine a text brush with another, more decorative brush, make one of them more opaque than the other.
