I usually bring a hand work project with me when I travel. I do all the preparation before I go. Have your fabrics ready to use. Yes, have your definite pattern. I'm not a fan of the English paper piecing where they sew the outside together. I would rather just sew along the seams, basic hand piecing. Your speed will pick up as you work on it. Set yourself up with a little kit with threads, scissors and fabrics.
