I found a magazine rack at an estate sale...works great!!!!

I have a vertical rack that I hang on my wall just above my cutting table. I also have a flat, horizontal rack that is next to my cutting table. These hold my big and square rullers (and a couple of weird shapes such as the FlipFlop ruler). My small ones and my specialty rulers are kept in a plastic shoe box on a shelf. I have more rulers that I know what to do with, but I really have this thing about tools - the more the merrier.

I also hang mine this way. My small/tiny rulers are in a drawer right next to the cutting table.

This is what I do as well. They hang on the wall next to my cutting table.

I have 2 plastic boxes. One is like the pencil boxes they sell and one is the kind they use for storing scrapbook paper. Probably not the best method but at lease I don't lose the small ones.

The big ones I use at my cutting table hang on my pegboard.

Small ones that I use with a small rotating mat at my ironing table fit nicely into a small open box on a small open shelf in my sewing table (I have the Janome universal table).

I have some of the large square rulers hanging on the 3-M hooks, some of the smaller ones in the flat horizontal ruler racks, and my tall ones are standing on end in a small plastic trash bin. I have a small sewing room and everything is within easy reach of the cutting table. Do whatever is handy for you.

I hang mine on the side of my sewing machine table

I Love this. I wish I had someone to make me one. Does he sell them? If so, how much?

Mine hang on one side of my cutting/sewing station. Love it, because they are at my fingertips when cutting and ironing. But still out of the way when sewing. And most of all I always know just where to find them, being tight on space helps me put them back to be used again another day.
