I covered a small board, a bit bigger than a fat quarter with insulated batting. I have the Rowenta travel iron, works great. When I pack the car, I lay my mat and ironing surface on the floor of the trunk and have not had a problem. Remember extra bobbins, needles and your cords and foot pedal. Cut what you can and bring a variety of projects. Sometimes its hard to know what you will be in the mood to do. I'd look in a thrift store for a large tote or suitcase. Oh and I always bring my own pillow
Have fun!!!
