Ok, so I'm about to make a purchase or two to finalize the hammock sewing part of my adventure. I'm feeling so-so confident that it's not too difficult, I've come up with a question I haven't found an answer to

The basic hammock pattern is rectangle, you just sew and fold edges/hems. With these different companies making hammocks, what is the difference in their shape versus what I would be making? Or is it the same, but with added features....

If I were to buy a hammock right now, the Warbonnet would be my first choice - secondly the split bottom one. The split bottom of course is different, but ow about my first choice - forget that it has a zippered bugnet. I'm assuming I can add a zippered bug net later if I have enough of a hem 1/2".
