You know that you don't want deep shelves, but since you already have some you might want to use them for you larger fabric pieces that, when folded, will still show from the front. I strongly suggest you put a curtain or some covering over the front to make sure they don't get damaged by dust or sunlight. You can do this by thumb tacking or by using a metal curtain rod (I'd put the place for the rod down a bit and thumb tack the top extra fabric down on the very top of the shelves to keep out dust; you can still use the very top for small boxes of your different tools, etc.

A lot of stores sell series of plastic boxes, with about 4 or 5 shelves each, that have wheels which you can remove if you want to store one on top of another. I use two of these for very small pieces (less than fat quarters) and still had to resort to "very very small pieces" boxes! (I do a lot of applique.) You also can get little storage bins for your labels, clamps, paints, marking pens and pencils (and regular pencils), store bought bindings, etc. Before I bought clamps I used one for clothes pins for holding the sandwich together until it was stabilized.

I still use large plastic bins for different kinds of batting; in my case I have a lot of smaller batting pieces for my appliques. The large pieces are wrapped in giant rolls or in plastic bags if they were pre-sized, and they go in "that part" of my sewing area so they are all together, smaller ones in a box.

One thing that I do a bit different from most quilters is that I have a lot of cardboard boxes, about 12"W x 18"L x 8"Deep with labels on both ends (one is upside down) with shipping taped tops that I can repeatedly open and reseal (by putting tape down below where the movable tape flap (with a folded over end of about 3") will adhere); I can put these boxes upside down to help keep them closed and safe because the labels can be read both ways (of course you have to put the side out that is "right side up"). If I start putting aside fabric for a future quilt I can put it in one of these. Also, fabric to be used only for applique goes into these boxes by subject (large baby prints; small baby prints; animals; cars & trucks; butterflys & bugs... you get the idea.

Fat quarters are an in between for me. All of my bigger fabrics are in a 4'w x 8'h x 18"deep cupboard and since it isn't "full" I have reserved a section for fat quarters. I'm (mentally) part of the challenge to use what I have, not buy new, which in reality means I only buy smaller pieces because sometimes you really need a certain color or design to fit into a quilt on which you are working.

I have 4 of those Joann fold down white tables but you have to put idustrial size 1" square patches where the pull out leg will sit and on the top of the leg itself or they can dislodge with the movement of your machine. Also, you must put your machine in the center over the permanent 4 supports... if you put it out near a corner w/o any support, that area will start to warp down over the years (duh....). This gives me a 10 ft x 6 ft working area, or any arrangement I need. I've had these table over 10 years now and love them. They fold up and can be stored to the side with ease.

Hope this is the sort of ideas you were looking for.
