There are lots of threads asking about this all the time so I broke down and did a few pics of my working mess. Here are the shots of how I organize my fabric.
The shelves for the major part of the stash came from a fabric store that closed. They are about eight feet long and six feet high.
The table is from the same store. It is 3 1/2'W x 8'L.
Scraps by color right above the cutting table
backing fabrics under the table. The LA in the far part of the room.
Main fabric shelves by spectrum system. lower right area fir B&W and specials
projects waiting at end of table and labled scraps
projects being worked on but on hold, labled and under my small ironing table next to my DHM.
Hope my casual organization helps some to not worry to much about being focused on tidy rather than quilting.
