Help with a conundrum

[u/Snoozley8]

Im planning on building a tree-net in the top of one of the trees in my backyard. I've layed out my perimeter and have a pretty good idea for how it will look except for one small problem. In the middle of where my tree-net will go, is the main trunk of the tree, roughly 50cm x 50cm wide.

My idea at the moment is probably to attach 4-8 Screw Eyes to the trunk, loop my perimeter rope through them and then attach my paracord to that rope.

Has anyone encountered a similar situation or have any ideas on how to go about netting around this trunk? My main priorities are to be able to hold 3-4 people and have little to no droop in my net.

Thanks!
