I haven’t made German Stars for a while. My family has no history of decorating with them. but my friend Deb’s family does. She showed me her stars one year, and told me that her German grandmother would dip the stars in wax. If you want to use wax, melt, then cool until a thin skin forms, then dip. The wax ought to harden right away. To add monofilament for hanging, glue a thread in the fold of a point. They are pretty in a bowl, with glitter glue painted on them, in different colors. I just like them.
