I'll be lighting my North Pole Shade with various LED rope lights, around the arched openings and around the top inside to provide muted illumination. But the hooking on part, I'm not not exactly sure how to do this. Surely not my most difficult task, but... Any ideas?
I have a similar Kelty shade, but with no screen, and it has a D-ring in the middle of the ceiling like a tent and small fabric loops in the corners. If yours has something like that, use simple nylon cable ties or reuseable "hook and loop" cable ties. If you're attaching the lighting around the "doorway," you won't have any attachment points so my idea is moot.
Or, go with AntiM's plan and use spring clamps. They give you an added advantage of having a tool for a fast emergency repair of something more important should you need it. But, looking at the photo, it doesn't seem like there is anything to which you could clamp the lighting. I mean, no storm flaps or loose fabric.
I would avoid gromets or any other means of making a hole in the tent, since it can affect the structure and degrade the fabric.
Maybe you can use small strips of steel, like what one uses to secure conduit to a wall and attach with a magnet on the other side of the fabric. Some tent lights and fans work this way. I don't knwo if it will make the fabric rip after a week in constant wind.
If you're really slick and know what you're doing, you could sew fabric loops or some attachment point to the fabric, seam-sealing behind the stitching. That will allow you to have lights and whatever else the fabric will support hanging off of the tent. Keep in mind the integrity of the structure may rely on the fabric being intact, so sewing or modifying may allow a structural failure in a strong gust.
If you go the sewing route, slightly over-do it and tape the seams. If possible, set up the tent and lean on it or find a friendly neighborhood hurricane and go camping.
