These note cards are literally one layer.
Cardstock blanks were stamped with Penny Black's "Decadence" in Onyx Black Versafine and then masked so a Teal Zeal Memento strip could be sponged on.
The decorated "flats" were paired with envelopes and enclosed in an acrylic box tied with a bow accented with an antique button.
