On page 108 of Butterick Publishing Company's Tatting and Netting is found Trimming, with Thick Loops and Fan Edge.
The instructions are fairly straightforward. They do not tell exactly what size knitting needle to use, but they leave it up to you to decide. I used a #5 knitting needle along with the 1/2" flat mesh stick they suggest.
The one problem I found was that row 5 should be deleted, at least if you go by the illustration included with the instructions.
I wonder what the edge would look like if, in the next to the last row, I were to skip 1 loop instead of the 3 loops the pattern suggests.
Several weeks ago I was browsing online for hairnets and snoods. I wanted to see what had been found before 1700. One hairnet that caught my eye was labeled "Hairnet, beginning of the 16th century, Linz Museum."
I liked the stitch pattern and decided to see if I could figure out how it had been made, just using the photo online. It took several attempts, but here is my version of that hairnet.
I made this hairnet as a rectangle, instead of my customary circle or triangle. That created a few problems for me at the upper corners. I suspect if I had sewed the cord to the loops, I might not have had the same problems - probably different ones though.
I experimented with different size mesh sticks and found that a 1/2" and a 1/8" seemed to give the same look and ratio that the online photo had.
I was surprised to find that the stitch was based on what I've called the Crisscross Decorative Stitch. The difference in look was created because this hairnet used one row of large mesh and two rows of small mesh. The Crisscross Decorative Stitch version used two rows of large mesh and one of small mesh.
