All my printed fabric is stored in the closet, I have most of it in plastic containers according to what sort of fabric it is--cats, kids, xmas etc..fabric i might be collecting for a project.
I have stacks of fabric for backings.
the second pic is where my solid color fabric is stored...under the yellow table cloth is 4 rubbermaid drawer containers-each color has its own drawer.
I have a tall slender bookcase I am going to add to the closet for fat quaters now that i found myself using them more.
