For me, I like my FQs accessible with my longer lengths of fabrics.
Anything over a metre is folded 1/4 WOF then to about a 6" width, and is labelled with painters tape as to the length.
Under a metre is folded like you would a FQ.
Shape tells me the basic sizing.
All are stored in plastic bins about 6" deep ... on end, so that when I open it up, I can see the different fabric and colour possibilities.
Bins are labelled (again painters tape to the rescue) as to contents and are sorted by colour(s), with extra bins for seasonal/Christmas, florals and birds, batiks and novelties.
