I'm definitely not as organized as some of you! I store my 8 1/2 x 11 paper in a fabric filing drawer. and my plain colored 12x12 in a magazine plastic paper storer thing from Joann's and some 12x12 plastic bins separated by company for my DSP. I don't cut it down either because I make different size cards. I save all of my scraps too that are big enough for anything and I keep those in shoe boxes. Black and white scraps are kept separately than other colors. And DSP scraps are kept with their respective companies. I try to use as many scraps as I can because they tend to add up.
