Did I put 4 or 5 cups of Flour in there?

I wonder if I'm the only one that gets busy while measuring flour and sometimes end up thinking "Did I put 4 or 5 cups in there?" and then later finding that you put either too little or too much and have wasted all the time and ingredients because of miscalculations! I have started taking my 5 pound bags of flour and immediately measuring out 1 cup, because I find that most recipes call for 1 cup increments and putting each cup in a baggy, and then place all of the baggies back into the flour bag so I will know later if it is, All Purpose, Self-Rising, Cake Flour, Pastry Flour, Duram, Whole Wheat or Semolina. Using the wrong flour for a project could make a big difference in the outcome. I then place the bag in the freezer. It takes a few minutes to get the flour measured out, but is totally worth it, I can just take the number of 1 cup bags out of the freezer and add to recipe, no muss, no fuss.
