"... enclosed solo tarp/tent"
Sounds more like a tent than a tarp, albeit there is a big gray area.
To attach netting to the Cuben, you will have to sew.
And to attach the Cuben to itself, many use clamping with the Hysol PU adhesive.
If you think sewing could be challenging, try clamping the entire length of every seam on a tent. A bit easier with a shaped tarp.
And even with clamping, the Hysol bonds can be readily peeled apart.
