For making these napkin rings you’ll need about 85cm of twine. Wind it three times around the first three fingers of your hand and make a knot with both ends. Leave about 5-6cm on each side and make a further knot at the ends to avoid unravelling. Fix the twisted ring inside the seashell with a little spot of hot glue. When the glue has completely dried you can pull the napkins through it.
If you don’t like the twine ends to be seen beneath your seashell just cut them off and glue the twine ring in the middle of your seashell.
