You can raise the privacy fencing on post #37 picture nr.3, if you use a tall post in the middle and stretch that fabric upwards. You could gain another foot of privacy. Or you can use that tree in the background, tie some strings to the middle if the fencing (for more strenght on the anchor point to the fabric, you can use some rigid bar that you tie on multiple points to the fabric, then you attach the end of the string to the middle of that bar). Also is a great idea to use two privacy fencing a few feet apart, so even somebody tries to look over, he/she can only see the second fence. Also the smell of the flowering plants will be diluted more this way.
Nice garden, best wishes.
Thanks a lot!!! Everything looks so amazing. Trying to buy support and netting.
