Q: 1. How does this valour material compare to westcott wrinkle resistant cotton material. Can you machine wash this material?

A: I've washed it and it didn't do anything weird. The velour material makes it really easy to setup without having to steam or iron it. Sometimes I will add some wrinkle spray to help it or pull the sides with some clips to make it seamless. We use two of these side by side to get a wider space and we haven't had any problems with keying. Smaller spaces I would use some magenta gel on the backlight.
