My cabinet is 48" wide x 6' high x 24" deep.
The very bottom has a tub of scraps, a quilt kit, some leftover batting. I used my 5 x 24" ruler to fold fabrics on. Large yardage pieces are folded selvage to selvage then fold to selvages. I have them behind the short stacks of smaller yardage pieces. Smaller yardage pieces were fold selvage to selvage and folded with the ruler, to see the back stacks, I take out a front stack and can see them.
