My personal feeling is that the big cardboard bolts from the fabric store take up too much room. Some people say that they're not acid free, not meant to hold fabric for a long period of time. I just fold my fabric around a 8.5"x24" ruler. It's nice and neat and doesn't take up any extra room that way. However it won't stand on end, so if that's what you want try the comic book boards. They come in a couple of different sizes and will easily hold 3 yards or more.
