You could use pallets. They are usually free or very inexpensive.
Can you give us an idea of the area you want to shield? Is it a balcony or a patio overlooked by a 2 story building, for instance? Is there an existing but "open" fence around some or the entire area that you could run some inexpensive and tall bamboo or grass panels and tie or tack on to the existing fence?
Julie....I agree with the pallets but take a look at the door fences people are doing. Just Google it. Sometimes people are remodeling and getting rid of doors. Don't know that I would want a whole fence but if you had a small section where they could be used it might be okay. Good luck!
I just bought a house and want to block out neighbors, there is no existing fence there now. I was possibly thinking of some sort of shrubbery, but would want something fast growing. Not sure. I have an acre of land, and need to block on just one side.
Thank you so much!!
