Here is a picture of my scrap system. I store each color in a 2.5 Gallon zip-top Hefty bag. Walmart has them for ~$3 for a box of 12. Then I keep the scrap bags in my Thirty-One medium utility tote. They fit perfectly and then I can carry them with me to scrap retreats. Sometimes I will go through the bags and clean out the smaller scraps and organize them by size.
