I have an embarrassingly large collection of art rubber stamps, mostly collected between 2002 and 2012. These are collages that feature rubber stamps, either as focal images or in backgrounds. I found it a challenge to incorporate stamps into mixed media work in terms of working with backgrounds and getting clear images on layered substrates. One technique, stamping on tissue paper, allows for backgrounds to come through, as the tissue paper becomes translucent when applied with gel medium or glue.
