How did you seal the ends?

No need to seal the ends. There is enough over hang that it doesn't matter. You can also gather and tie the ends of the bug net around the ends of the hammock which makes a tighter fit but I never had to mess with it.

I've seen people try velcro but the netting gets stuck in the hooks and can rip. Just let it hang like a bug net over a cot.
