Lowes has a good one that is used for keeping birds off of fruit trees. Thats what I used. Comes in a roll that when opened is 7'x50' Works for me and is inexpensive.Its also known as deer netting. Hope this helps.
I recently ordered some knitted netting from a company in NJ called Endurance Net. They have a great selection of closeout netting so I was able to get 6.5 x 50 for $50 SHIPPED! This is the 1" heavyweight that will hold up to the Maine winter.
I highly recommend this company. Every other place I looked at wanted to sell a whole roll and then shipping was by truck. My 50 feet is coming UPS.
