It's that simple:
1. Knot one end of the sisal cord to the metal ring and wrap it around the centre of the ring several times. Stretch the cord over the ring and wrap it around the ring. Repeat the process. Knot the end of the sisal cord.
2. Weave individual filigree dried flowers into the cords.
3. Also knot a piece of sisal cord to the metal ring for hanging.
