I had this all figured out but it took 2 people to lift it into the car. So I started collecting for weight and size. Sewing machine under 15 pounds. Cutting mat folds in 1/2 so it fits into a smaller tote. A towel for iron mat and small iron. A seat pad ( the towel and seat pad cushion my machine). Electrical cords. Small trash/pin cushion with only 3 tools (scissors, seam ripper & awl). I'm always the hottest person in the room so I always have a fan. It all fits into an office file on wheels that folds up.
Usually I just need to add fabric, tread and 1 template
