Insert 1 pearl into the wire mesh tube and push to the middle.
Make a square knot in the mesh on both sides of the pearl, leaving enough slack in the mesh around the pearl to pull the mesh into a small oval casing.
Working from the middle out, repeat to add pearls between knots along the ribbon, pulling the mesh into small ovals along the way.
Leave about 1.5 inches of ribbon at each end after the last knots. Insert 1 pearl, then crimp on a fold-over ribbon crimp. Repeat for the other end.
Use pliers to open and close jump rings to add a clasp.
