When cleaning the BBQ last night, some industrious little spider had managed to get build a web in a gap some 2 meters wide between the BBQ and the tree and I thought how did he actually manage to bridge the gap to begin with?
Do they jump like some tiny eight-legged athlete, paying out rope as they fly through the air? Do they run down across the ground and then back up again? Do they perch on point A and fire a line across the gap line some little butt sniper and then build the rest off of that?
I am perplexed.
Edit: please forgive the illiterate title, insomnia’s kicking my ass at the moment.

They let out a strand that blows in roughly the right direction so that it sticks to something out that way, and then they adjust it as needed. They might need to try a few times.
In your case, the spider started from the BBQ or the tree, let out a long thin web that blew across to the other side, shimmied down the web to the other side, and then moved that end to get it in the right spot. After there’s a good horizontal bridge line across the top, it’s all systematic.
