You might try going to a craft store and looking at their clip art books and alphabet books. You could probably find free clip art sights. I got books a few years ago to do projects with my students. I used an opaque projector to trace the images I wanted to use and then let them do the painting. I don't know why it wouldn't work for applique. More work, of course. Are you wanting a quilted banner or one on canvas or muslin?
