I have open shelves for large pieces of fabrics. They are ruler folded and grouped by color and theme. I use the plastic shoe boxes for 2", 3", 4", 5" squares, jelly rolls and charm squares. I use the next size up of the boxes for layer cakes, fat quarters and grouping all the fabrics for a certain project together. I use peel off labels, so when I actually finish something, I can relabel and reuse the box. I poked a few holes just under the rim of the boxes with an ice pick. I've used this system for years without any problem!
