Mine used to look like this. Even after I cleared up the clutter, the room always looked messy. I was so there...
I can help you with this:
I did the plastic bags with zippers (not firm enough-shifts)
I did the plastic bins (couldn't see what I had)
I did the plastic sorted containers (small w/handles - took too many)
I did the file cabinets (wanted to see them - too many dwrs.)
Finally decided the quilt shops knew what they were doing and started using fabric boards to wrap my fabric on - now I can see everything I have. Started cutting them for people here on the board and must say those of us that use them will never go back to using anything else.
You can see that my shelves are deep too. So I put large boards in the back and mediums in the front. Mine are 18" deep. The very best part is - I can see everything and don't have to buy much because I see so much that I already have and want to use all I have to do now is choose patterns and fill in a few pieces to complete the package for a particular pattern.
Here's the link if you want to get some from me.

Whatever you go with - happy organizing! It is 100% worth the trouble and clears up all the visual clutter when the room is clean. Best part is you can feel it and be so much more inspired.
