Print the stars template and cut out the stars. Set the stars aside for now.
Divide the toilet roll into thirds.
Cut the toilet roll into segments following measurements.
Tape the beginning end of yarn to the inside of one of the toilet roll napkin rings.
Wrap the yarn around the napkin ring. The amount of yarn you need depends on the type of yarn you are using and how snuggly you wrap the yarn. I used about 14′ of acrylic worsted weight yarn for each napkin ring.
Use white glue to glue the end tail to the inside of the ring.
Secure the glued end with a binder clip or paper clip until the glue is dry. Trim any long ends.
Glue the stars you cut out in Step 1 onto the napkin ring.
So the stars show up on the white napkin ring, outline them with red and blue marker.
