Hi KTF,
Will you be doing these alone, or will you be having help from kids?
Two that I made with my daughter that I liked were jelly jar votives and tube sock snowmen filled with rice. There not ornaments, but they're Christmasy. We sent the tube sock snowmen as gifts. We gathered together everything needed (except the rice) and sent it to people with instructions so they could do the craft themselves. It was pretty cheap, but relied on creative presentation.
