This seems to go against common practice of standing it up, but does anyone do it?
I roll it up tight and either use some gaff tape or rubber bands to secure it, then slide it back in the box. But I have finally helped my mom clean up her garage enough to have a proper sized studio and have gone from short rolls to long rolls. I don't have the ceiling height at home, and her garage (plenty of height) is not climate controlled. In North Carolina it gets pretty humid and I think maybe the humidity would be worse than my current plan?
I have a flat brick wall at home that would support the entire length of the roll.
