I was dizzy the first 3 days of a 6 day cruise. Can't imagine trying to look down and concentrate on sewing. Although I'd go on the Bali batik cruise in a heartbeat. I think it would be better to take classes on land. Go to one of the big shows, Paducah or Houston and take a class from someone who you love their patterns. I felt sick and lost weight . Certainly didn't get to enjoy any of the good food in front of me.
