Overlap lace doilies on an inflated balloon and brush fabric stiffener (or wallpaper glue or white glue) onto the doilies. Be sure to cover it completely so that the whole thing hardens and you aren’t left with limp spots. Let the doilies dry overnight to ensure that they are completely dry. Then pop the balloon and pull it out of the opening. The lanterns can be hung with a ribbon or fishing line.
