This was a tricky color combination, but the first thing I thought of when I saw the colors was that the combination would be perfect for a Halloween card.
The witch hat stamp is a $1 stamp from Joann’s. The “Priceless” saying is from DRS Designs. Background paper is DCWV glitter stack and cardstock is Bazzill. Inks used are Ranger Archival (Jet Black) and Colorbox Fluid Chalk (Warm Red).
