I have seen a lot of ideas on storing little bits of fabric - plastic boxes, big glass jars, hand-made patchworked boxes without lid, ...
always organized by colours.
but how I store mine? well, when I started, I was organized. The more fabric I got, the system was disappearing. and now I have fabrics everywhere, in every draw, on every shelf, on every coathanger, ... well, I am definitely not an example to follow :-)
