I used MADJAK stamps from Linda at firstname.lastname@example.org for all these Artist Trading cards - using different mediums for different effects.
The Wedding - stamped on music score paper, embossed matt black, and burnt border. This is darker in reality - and the border is dark burnt brown - achieved by using lemon juice and a heat gun.
Water coloured camouflaged type backing paper with silver outlines. Stamp reversed on acetate and edged with silver embossing
Little Boy Blue
Background paper blue shades rainbow, image stamped with a complementing blue ink and heavily embossed - so has a shiny dimpled texture.
Distressed ink background, stamped embossed face, border distressed red embossing.
Unfortunately the scans do not show up all the textures of the embossing - these are very touch feely ATCs.
