Do you want to celebrate the rainbow without adding too many artificial colors to your food? Look through your basket of old ribbons and notions -- I found a spool of rainbow covered ribbon and afixed it to some old napkin rings. Or, consider using a different color ribbon as a napkin ring for each napkin -- make your whole Shabbat table look like a rainbow!
Different colored ribbons or rainbow ribbon
Old napkin rings or a glue gun
1. Cut ribbon into 3-4 inch strips.
2. Either affix ribbon to old napkin rings using tape or simply hot glue the ends of the ribbon together.
