Using the 28g wire, coil it 2 or 3 times around the heart frame and the bottom bend to anchor it.
Holding the first link of the chain against the frame, wrap the 28g wire through the link 4 times.
Then wrap the frame 4 times.
Skip the next link, so the chain sits properly, then attach the next link.
Continue attaching every other link up the side of the frame.
