Gesso Stamping

There´s Gesso on most of my artwork, but here´s a technique that I don´t use very often: Stamp with Gesso on a dark glossy paper (here it´s dark blue), let dry (and don´t forget to clean your stamp immediately); then wipe different dye inks (here it´s oriental blue and deep lilac) on the gesso and wipe them away partially.
I´ve also used Gesso to glue on the transparent butterfly to give it a white background.
This card is my entry for this week´s Wednesday Stamper´s challenge on Gesso.
