I didn't have a schedule but it has worked out that I've refolded my fabric several times in the past few years. I think it is a good idea as it lets you see what you have and also mitigates fold/fade lines if your sewing room isn't as dark as you think.
I ruler folded twice (different sizes when I changed shelving) and now most is on comic boards (1-6 yds), with less than a yard folded like a fat quarter, & 6+ on a bolt. I need to stop buying fat quarters (I'm at 438 fqs and haven't even finished - yikes!). : )
