Do the pop up backgrounds look creased when used?

[scottduffy]

Guy's i am just about to order a 6x7 pop up background and i was just wondering if anyone who uses one could tell me if they crease easily and will i have to remove these in photoshop?

I was going to purchase black and white double sided. Just so you know what i'm getting.

I have a Interfit or lastolite 1.8mx1.5m with no train and not a crease.

I have a photodeals one (2.2m sq) and the train does crease a bit and the bottom corners crease a bit too, there are a few small ones in the main part but never show on images.
