The double picots in this pattern proved an interesting feature. The second thread gap after the ring, needs to be longer than the first to accommodate the inner picot. The top is tatted in Lizbeth Size 40 Col. 137 Berry Burst and the bottom is tatted in Lizbeth Size 20 Col. 132 Tropical Punch. Pattern is from the Tatting Artistry of Teiko Fujito on page 74. The double picots in this photo were not very obvious. You might have to click on the photo enlarge it.
