We have lived in the same place for 44 years. We have no plans to move until leave permanently. I have moved from room to room several times. Think I'm about done with that also.
I like the idea to pack all sewing items and fabrics in boxes and marking contents on all sides. You could just stick all boxes in the room where they will go. When you get the main things put away, then concentrate on the sewing things. I think that would work the best. I would not use my fabrics for packing. More logical to keep all together.
I like dejunking before the move.
Good luck and hope all goes well.
