This is another edge we figured out while flying across country. This is the middle of the three doilies pictured with the title Plate Doileys with Nettted Borders. It is found on page 130 from Tatting and Netting. Here is the netting without the embroidery.
Back in November I started making Arctic Circle. Then life got busy. I finished the doily but did not "find" the time to starch it until recently. It measures 20 inches in diameter.
The triangles made me think of icebergs, while the French Knots reminded me of snow, and the Eyelet Stitch called to mind ice floating on the ocean.
