Crest of the Wave
From the Stitch Description: Here is a variation on the much-varied Feather and Fan Stitch that is a little bit different from the usual very simple ones. This pattern too comes from Shetland and is used in making delicate lace shawls. Easy and uncomplicated though it is, it is very pretty and would be an asset to any lace garment.
