I have mine stacked by color too.........the problem I see is, when I want a piece and its ALWAYS on the bottom, and it messes the others up, when I go to pull it out..........so how do you figure out some other way? I like the idea about using the boards and stacking sideways like the quilt shop.....but my shelves are deep, so that would be a lot of wasted space........guess I need more shelves, inside each cabinet. Thanks for all your suggestions, makes me want to fix mine better.
