I'm exploring ideas for making a tarp as a lightweight shelter. I'm thinking a simple rectangle.

Most of the projects I've seen so far use webbing or grosgrain ribbon to create tie outs. One project I've seen uses grommets.

We've considered the differences. If we want to put the tarp flush with the ground, grommets work better. Grommets provide more flexibility to what you attach the tarp to, i.e. you don't always need stakes. (though its easy to attach a loop through the grommet so you can use stakes)

If I want a tie out along the center ridge line, I need a webbing/ribbon loop. loops are, perhaps easier to use.

Are there other pro/cons to grommets or tie outs? What is your inclination?

Thanks!
