Anyone Know If You Can Walk Through a Pipe/Drape Set Up?

It depends on the set-up-- most don't have anything going across the bottom, but some do. I think they're not really answering your question b/c its a little bit of an odd idea, and it probably won't work out how you imagine it. . . the structure really need to be completely covered in draping, b/c it's not designed to be seen, but that will make it hard for people to walk through. They're also not the MOST stable things, so it's not something you really want people interacting with-- pull the drapes back, walk through, repeat. .. it's just more than they're designed to handle. I would suggest looking into arches that incorporate some kind of draping. First, they will be way more stable and safer to walk through. Second, they are usually designed to be aesthetically attractive, so they don't need to totally be covered in drapes. And finally, you can use a lighter drape so its easier for people to walk through over-all.

I think if you are using it as an entrance-way you should take into consideration the following

1. What support do you have for this pipe and drape? is it just the pvc pipe as a 3 sided square/rectangle? Will it be weighted down? Usually for trade shows no one is walking through them, and I would think that if people are going to be messing with the draped portion, you should have them weighted down on either side

2. will you pull the curtain back ahead of time? Or do guests have to continually pull the curtain?

3. Will these be thin curtains? sometimes the fabric is pretty flimsy and looks more tacky than functional

4. as @barbara states, what type of framework are you renting? some frames have the center post for stability, while others are just an outer frame.

The first example on this link http://www.rkpipeanddrape.com/Information/257.html seems to be your best option of how to include the pipe and drape while ensuring that it won't fall over and is weighted down

I don't think pipe and drape will work with what you are imagining. It is used mostly for covering an area or giving a backdrop. It's true that it isn't the most stable thing on the planet. It would have to be affixed to something like the ceiling of a wall for you to move a curtain and walk through. If you watch David Tutera, they will have someone come in and set up this huge, heavy metal structure (can't think of the name) that holds the draping. That is more likely what you would need.

We had a piping frame for our ceremony backdrop, to hold up some butcher paper. It did have a bar at the bottom and I don't know how it would stand without it...it was very unsteady as it was.

(Excuse the tulle, I was not happy with how that turned out...)

We are actually getting married at a gazebo, so we wanted it at the beginning of a pathway, similar to the picture below. The curtains will be tied back before the ceremony begins, no one will need to touch curtains. The path is only 5 feet wide, so I was assuming the base would be off the path.

I will definitely ask the rental company if I should rent extra draping for both sides. The florist is going to provide flowers for the "tie back" of the curtains
