My neighbor approached me asking if I could print a banner for him to put up on his construction sites. Here in Germany, it's called a PVC construction fence banner, which is secured with grommets and ropes in a frame. Unfortunately, I don't have any experience with this and would have a few questions for the experts. To press the grommets into the material, you need a grommet press – I saw that in a video. However, what I didn't fully understand is that the edges need to be folded over, and one person welds them with a special device while another simply tapes them with double-sided tape. What is the correct approach here?
