What is ruler folding? I keep all my 1 plus yd pieces together. I store mine by theme and if possible color. Much are children's prints. Cuts are kept together. I must use plastic tubs but have 1 armoire that I mostly keep flannels,twill and upholstery fabric in. You have done a marvelous job...you are to be congratulated. Mine looks like that for a few days and then I go back to careless/tired.
