Here is a demonstration of the material strength. We made a banner 3’ x 10’. We put an extra grommet on each end for this test. We screwed each end of the banner onto a board. We attached one edge to a tree and the other edge to the bumper of a jeep. We backed up until it was relatively tight. Then we sat on it. See video at the bottom. This the same material we will use to print your banner. NOTE: Banners are not hammocks. We just did this to show you we’re not using cheap vinyl some sites do for banners. This is a high quality material and very strong. The grommets did start to pull out, so a load this heavy is too much for a banner.
