One option is to cut it up. The one at the top is an ATC size, about the size of a playing card. I attached it to the cover of my 2012 Sketchbook Challenge sketchbook. The red one below is on the cover of the 2011 sketchbook. Yeah--all year, it's been a plain cover--until now! Just a splash of color does wonders for a blank canvas.
My blogging friend Vicki Welsh at Field Trips in Fibers shows how to make Christmas Ornaments with a similar collage technique.
