Take 4 nylon loops & slip knot them.
Tie a knot at one end for the center of your rosette.
Roll & twist it while hot gluing into rosette
Repeat this process for however many rosettes you would like.
I used 4 loops for small rosettes & 8 loops for the bigger one.
For the necklace part just do the slip knotting until you have the length you like.
Hot glue rosettes to necklace & let dry.
