So far my collages have been on the small side, mostly 4" x 4" chunky book pages, but I've been wanting to do larger ones, so this one is 12" x 12". First I applied one coat of buff titanium Gesso (yes, colored gesso that I discovered during one of my visits to the local Daniel Smith store), then the vintage music sheet was added. Since the music didn't stand out as much as I wanted, paint was lightly added (I think it was Quinacridone Gold). Two birds were added to fill it out. The base is an almost ready to hang (just needs the hanging hardware) hard surface from Ampersand, called Clayboard smooth.
