I call this the Chinese Coin bookmark because the shape of the individual repeat is like an ancient Chinese coin. Click here to find out about the different type of Chinese coins that were once used in China.
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. To make it in one pass you will need to know how to make split rings.
