There’s a 2x4 running along there. The bamboo garden fence material pushes away when we wedge the bill in and that’s it...
The bamboo fence is usually available at Home Depot but not this year. 6’ high and 16’ long. We tie grass to it using tie wraps and gut to size and height with a cordless hedge trimmer. Just use stakes or rebar to support, or if on a fixed blind, we tie wrap it to the posts.
