Cut a length of leather cord measuring twice as long as your wrist measurment plus 2".

Fold your cord in half and secure to a board or work surface.

Cut a long length of grey cord and thread under your leather cord.
Start your macrame knotting approx. 0.75-1" from the folded end of your leather cord. This section of cord will be your clasp to fit over your heart bead.

When you are near the end of your leather cord, wrap your bracelet around your wrist to see how much further you will need to knot.
Once you are happy with your length, thread your knotting threads through your heart bead and position it on top of your bracelet.
Wrap and knot underneath the bead to secure. When you are happy with the security of your heart bead, trim your threads and leather cords neatly to finish your design.
Your bead and loop of leather create a toggle clasp.
