I only let myself work on 2 projects at once. So I have them in 2 neat stacks on the end of the cutting table. I have a 3 drawer rolling tote with the next 3 projects to be done- 1 to a drawer, fabric and pattern. Nothing done to them, just ready to move up a drawer. Won't let myself work on them until the 2 in process are finished. Prevents creating wips.
I have totes 9 with fabric, 2 smaller ones with scraps and then the drawers of fat quarters in dresser.
