I have tried several times with no luck. I have decided it 's not supposed to go back in. This reflector is made for the studio and not easily mobile. They are nice, but not really what I was looking for. I'm a little disappointed.
This should not negatively effect the reflectors ability to bounce light. My reflector is wrinkled up except for when I use it and I have never experienced any issues with the wrinkled reflectors ability to properly light my subject.
Sorry, I didn't mean to offend anyone but putting this together is as simple as lacing your shoes. Why don't you contact the manufacturer if its causing you such a headache. Maybe their support team will walk you through the setup,
