So we have a contract to produce a boat-load of Drone/Survey targets. The size is 48" x 48" and will be secured to the ground by means of regular grommets around the border using long spikes.
In addition to the hem grommets,
They would like to have one large grommet or HOLE in the center of the "target" which they can slip over a survey spike. They will periodically do additional aerial surveys (one every 4 months) and would like to replace these targets over these permanent survey pins again (they will not be leaving the banners on site between flights). They need a 1-1/8" grommet. I do have the that size, along with the die to set them.
My questions,
1)would you beef up this hole with a 3" x 3" piece of banner material under that hole?
2)Would you use adhesive to secure it, or just put the grommet through both pieces of banner material?
Perhaps it wil be fine without any "beefin-up?"
The banner is a 13oz scrim material.
