I'd love to participate in this challenge at the CAS on Sunday blog, but I have the awful feeling it might be too many layers to be strictly "Clean and Simple."
This card was one of a number of similar cards in what's essentially a single design in different colorways. The cupcake tower image is from Peddler's Pack and was stamped with VersaFine Onyx Black ink on what's probably a generic white cardstock, but might even be Neenah Solar White. There are three shades of purple Bazzill card stock, with Hero Arts' "Envelope" background stamp inked with VersaMark on the light vertical strip, and the three light "ribbon" strips stamped with an Inkadinkado background stamp also inked with VersaMark. Nothing was popped, and the card ended up going to a BFF for her birthday.
Oddly enough, that's not the first essentially monochrome birthday card I've given to BFF-M!
