Sticky stuff! This stuff is amazing! You cannot see it unless you look for it. It has little "barbs" built into the fabric so you can literally stick it to tree bark and it holds. I started tying it off but then realized there was no need on my trees since they had uneven bark. I am sure you would have to tie off to a smooth bark tree but on the ruff bark all we did was press it on the tree. On the sticky subject, it sticks to everything. I felt like I was a hobbit in a spider web. I had to just laugh and carefully untwine myself. I think the fence is perfect for small animals or occasional light deer deterrent. I am not confident it will stop our copious Bambis much less Momma Bambi and certainly not the Master of the House buck. After discussing it with some gardening neighbors and well as the person who delivered it from Amazon, we decided to change to a 600 pound test deer fence (Tenex) but am doing so with a heavy heart.
