    Straps or Grommets for Tarp?

    The seamstress has finsied sewing the seams for my 12 x 12 tarp. I had her sew 10" triangles in the corners on both sides of the tarp and 6" x 6" squares in the middle of each edge, again on both sides. So I feel certain that there will be enough material to support either grommets or sewen in loops. I'm leaning toward putting in grommets - only beacuse it is easier and cheaper. any suggestions?

    Don't do grommets... Sooner or later even the best grommet WILL fail/pull out... Straps are far more reliable and sturdy long term...

    Don't save a couple bucks and risk wasting the whole tarp. Use sewn webbing loops they distribute the force more effectively.

    Do you have one of those special grommet presses? I have not had good luck with grommets, but I don't have the "proper" tools. Just a BFH (big f****** hammer).

    Even with a proper press they don't work as well as sewn.... Better, but still not great. Sooner or later they slip or the material stretches some and they start to come out. The only place I've not seen it happen is on HEAVY duty sails where there are MANY layers of no stretch fabrics all carefully sewn and joined (Like head/foot/clew.) These areas are VERY stiff and rigid so the grommet holds well. Your tarp isn't going to be like this.

    I just use the walmart grommet tool - a two piece grommet holder that you hit with a hammer

    That's what I've tried using. I never seem to get a flush set; probably operator error.

    take 1" wide strap give a half a twist and then sew it on to your triangles you have in corner all tents seem to be made that way for steak outs and that way if instead you will have to find a groument that will have to be big enought to accomadate you treking polls. this way it would be sure to fit.

    JMHO and that is how I would do it when I go buy mine.

    I am trying to find a patteren or a way to make the cat cuts on the tarp now so that I will do it right not sure how to make the cuts and make them a clean nice smooth curve.

    i agree w/ rapt. you don't see grommets on any of the quality, light weight tarps offered as far as i know.
    a properly sewn loop of grosgrain or webbing will give you more security when the wind blows<g>.
    don`t leave the CREATOR out of the creation!
