Collage or Quilt?

Is there a difference? It's not all neatly pieced like a quilt but the pieces are sewn together. This was my first attempt at art quilting. I saw an art quilting magazine at Mama's house and I needed something fun to get inspired. Once I got started I couldn't stop! Mama has since sent me home with a stack of quilting books. She's determined to make a quilter out of me! Of course, I do have a huge stash of fabric for someone who doesn't sew much. Maybe this will be a good way to use some of it. I'm interested in incorporating some other media into the quilts now like paper, ephemera, etc. We'll see where it goes!
