So I tried the L, XL, and Gigungo-sized Space Bags, and they seriously helped my space issue. The linens/pillows that I put inside the bag are now taking up 1/3 of the space that they were before. I didn’t think about it at the time, but we bought the Space Cubes, not the flat bags. Next time I will buy the bags, because the cubes make these really weird shapes that don’t stack well on top of each other. I went and reread Sarah’s blog and saw that she mentioned this, but at the time I didn’t make a mental note.
B++ to Space Bags for more space.
