I find this design interesting because it can be made in two ways. You can either make individual motif and join them up, or in one pass. It can be a very colourful piece if the individual motifs are made in different colours.
This pattern requires knowledge of how to make split rings. The split rings are marked in colours green and red/purple in the chart. The green split rings and balanced, i.e. the stitch counts are equal on both sides. The split rings in red/purple are asymetrical, i.e inequal number of stitch counts on the flip and unflipped sides.
