I used the brand new Butterflies & Blossoms set that is just being released from Flourishes for this!
After I stamped and masked, I colored the butterflies up with Copic markers and used the Tigerlily, Flesh Tones 2 and Cool Neutrals collections grouped by Flourishes. I used the drop shadow technique and just shaded the areas that might have a shadow. I started with the C05, and then added C03 and C01 and blended with C00 to create the look. After I was finished, I matted it up on some Basic Grey Ambrosia paper, added a punched sentiment (from the set), added some black bling and some ribbon and... done!
