I have been creating collages using archival mat board as a backing, because it is sturdy enough to withstand paste and glue without buckling. However, it is not easily stitched through, and I want to use stitched lines as design elements in new collages. So today I played with alternatives. I'm not fond of batting --- too puffy, plus what to do about the edges. Finally I hit on the idea of using Pellon, and I think that is the solution for me. It is somewhat sturdy, yet easily stitched through. The collage above is my first attempt using Pellon as a backing, and I'm happy with the way it handled stitching and painting. What do you think?
