All of the above lists are great.
This is how I pack for 1 day sewing.
First, I have a rolling sewing machine bag that stays packed with machine, cords, cutting tools, ironing tools, pad for the chair, seam ripper, scissors, stilleto, mechanical pencil, paper, loaded pin cushion, trash bag.
Second, I decide what project to work on. Then gather all tools and cut fabric for that. I would pack a back-up project.
Since I have special dietary needs, I pack all the food and drinks needed for 1 day. And my medicines.
Dress in layers. I'm usually hot, so I take a personal fan.
Lighting may be an issue.
A great attitude: Have Fun.
