This ATC uses some of the techniques Tim Holtz demonstrates on his 2009 Day 7 Tag (12 Tags of Christmas).
Choose a main image and stamp it on a mask sheet with StazOn ink and cut out. Stamp same image on Manila card with black Archival Ink and let dry.
Cover stamped image with the mask, then stamp flourishes with white acrylic paint. Remove mask and wipe acrylic paint off of mask.
