Here's a scheme that might be useful for you ... a post and swag screen that uses vines for cover. The advantage is controlled height and limited spread in addition to ultra rapid cover (in weeks, not months or years.) This is two different methods to achieve the same thing, with the chain and string scheme being the less expensive, easiest to install and easiest to remove, if necessary ... even on a temporary basis. Annual vines cover quickly, but need periodic replenishment. Perennial vines usually make serious headway during their second year. The posts (and chain) must be sturdy. Use thin wire rope hammer-stapled to posts for the other method.
