Here is the 7 inch mesh Trellis Netting I use:
You will need to cut "panels" that end up with 3 "good" strings at 0 inches, 7 inches, and 14 inches. Then for the long dimension, you will need 5 "good" strings at 0 inches, 7, 14, 21, and 28 inches.
Then, you slightly stretch the ends of the panel over the double-wrap ends to seat within the grove:
After you cut (and test) your first panel, you can use that as a template to cut out more of the panels.
