I use collage in my sketchbooks to develop ideas and then techniques follow on into finished contempoary pieces.
I use layering of medias to develop ideas and the depth of texture and meaning.
Here is some of my work,
Old Rabbit Collage
This collage is based on the Medieval importance of the rabbit and was part of my Roadkill Exhibtion.
I also use collage in many of my community projects because it can be used with many differnt medias with a variety of topics.
See my website for many collage projects.
