Thanks for the interest.
I made the red carpet base from a sheet of MDF and some red material i purchased from a local place that sells cloth. I just picked a "red carpet" material. Rich, and bright red.
The brass uprights i made from brass tubing which i had filled with resin. When the resin had set, i chopped the tubing into equal lengths, and screwed in the brass bottoms, which i found in a local ironmongery store. When you buy brass handles for a kitchen cupboard, the sometimes have these parts as a decorative fitting between the handle and the cupboard door.
The corded rope was bought in the same store as the cloth.
The backdrop i made in photoshop and had printed out on vinyl by a local vinyl signmaking shop that normally makes large vinyl decals for the side of trucks or company signage. I got it sized at 914mm wide by 452mm high but, on reflection, i reckon it was too small. I have to go in close to not reveal the edges. If i got one done again, i would get it made bigger.
Here is the marvel backdrop image:
I also used that for the "Red Carpet" Avengers picture i did:
And some pics of the stage:
