I have recently discovered 2 1/2 gallon Ziploc bags. They are great for storing fabric, quilt blocks, notions, etc. Another idea is to spend some time cutting your scraps into more usable items such as strips (2 inch or 2.5 are good sizes to use) or squares of sizes that you can later use. I have created containers for strips of various sizes and squares of like sizes. Someday I will have enough collected to do a quilt. I can also look in the container when I need a strip or square of a certain size. When I am cutting for a quilt, I try to cut my scraps into these sizes that can later be used.
