Eight is an auspicious number for the Chinese. This is because it sounds similar to the Chinese character for prosperity or wealth.
This is a pattern called Eightsome Reel from Mary Konior. I enjoyed tatting this. Quite an unusual pattern. This is done in Flora Cotton thread size 20 in pink (#211). Top photo was taken after blocking and orientated at a point. Photo with black background was taken before blocking and you can see why it is called eightsome reel.
