I starch, steam press and fold my fabric in half with selvages together then fold it in half again. I trim the first end with my rotary cutter so it is even, then I fold it around a rotary cutting ruler that is 8 inches wide by 14 inches long. When the fabric is folded around the ruler, I slide the ruler out, trim the end of the fabric evenly with my rotary cutter and use a water soluble marker to mark in the selvage area how much fabric is in the piece. Then I straight pin it so that it will stay neat. I store my fabric in color marked plastic bins on its side so that I can see what I have. These pieces can then be pulled out for a project - I know exactly how much is there and the fabric is already folded and ready for rotary cutting.
