I need to organize my fabric also. I haven't figured out a way that I like yet. I have lots of fabric lines, like yardage, fat quarters and jelly rolls and layer cakes of a certain line, so it's hard to organize that. I just put it on my bookcase together.
All my fabrics are in drawers, not organized at all. I need to use a ruler and fold them and put them together by color. I've done that with my greens and reds only. I have a drawer of beige and tans that need to be folded nicer.
I have lots of scraps that are in drawers and not folded very nicely. I have small scraps in doctor bags that I could probably go through and organize by color. I have a lot of organizing to do!!!
