We spend alot of traveling in our motorhome and I take my sewing along. It is alot easier if you can do your cutting ahead of time and make kits. I sew on the dining room table and alot of the time we eat on the sofa on trays so I don't have to put my sewing away. :)
I too use one of the sewing/pressing mats and put it on one of those fold up tables that have the 3 different heights and have it next to the table. You don't have to get up to press, lol. One of my favorite blocks to make is the string block and I cut out the muslin foundation beforehand. Where there is a will, there is a way! Happy sewing and travels!!
