This may or may not be what you are considering, but for me it works. After organizing as suggested above, labeling, shoe box/tackle box, I put all my quilting work in one roller bag. My personal stuff all goes in another bag. I also plan what I want to accomplish and make "Kits" with pattern, fabric, thread in a clear single bag. I have a local shop that used clear plastic bags. Perfect for holding my retreat kits. This also lets me know what templates I will need. Don't forget spray starch or what ever you use. I do take a small table and a mini iron. Ask about the chairs that will be available. Some folks take their favorite chair or back support device. Then in the end if you forget something.....stand up and ask. This is a wonderful way to meet and greet the rest of the folks at the retreat! Have a marvelous time.
