How do spiders build horizontal webs.

With the use of gravity spiders can build vertical webs, but how do they build horizontal webs?
Spiders that build the familiar orb-shaped web usually start with a single superstrength strand called a bridge thread or bridge line [1]. The telescoping protein structure of this silk is believed to gives it its strength [1]. First, the material for the bridge thread emerges from one of the spider’s specialized silk glands and is formed into a strand by its spinnerets [1]. The loose end is drawn out by gravity or the breeze and allowed to blow in the prevailing wind, a process called kiting or ballooning [1]. A single bridge thread may be left in place overnight to mark a spider’s territory and a desirable starting spot for building a web the next day [2]. Spiders spin webs in almost any direction you can imagine [3]. If a spider puts a web in a place that is inconvenient for me, I usualy take a small stick, scoop him up and move him to a more out of the way place [3].
Spiders build horizontal webs using the same method as vertical webs, but with the use of wind instead of gravity [4,5]. To build a horizontal web, a spider will spin a single strand of silk called a bridge thread [1]. The spider then lets the wind carry the thread away from it until it contacts and attaches to something [5]. To strengthen the thread, the spider may reinforce it and use it to start the web [2]. If the bridge thread does not attach to anything after being blown in the wind, the spider may consume the thread and try again [2].
