To bury the heart, insert the marlinspike where Strand 3 was first tucked. Then
set the heart across the wire and behind the spike. This motion or method is
different from tucking. For lack of a better description, we’re going to pry the
heart into the center around the existing heart for several inches (G). You’ll get
the knack pretty quickly, because the wire will bind your tool if you’re doing it

incorrectly. Bury the heart for 6 inches (150 mm) and tape it to prevent the end
from springing out.
