you can get low voltage led strips reasonable and could provide light and be nearly invisible

These might help:

I just bought a 6m x 3m gazebo/marquee type thing and I'm planning to have a little get together party. I need some type of cheap lighting. I want it so it's dark but see-able. I was thinking fairy lights around the perimeter of the poles but my family friend said once they spread out it won't be very see able. Any ideas anyone? I want it to be nice not just lamps around the place as well thank you in advance.
