i got to know how to do the knots from a book,but i did a variation of the necklace.once you learn a few knots you can make bracelets,anklets,earrings,necklaces etc.hope you have as much fun as i did!! :) for the second necklace i used a 'prosperity knot'.done with satin cord it may be abit flimsy but just brush over it with some glue+water and VOILA!!hope you enjoy my first project!! :):):)
