I use dept store and speciality bags - the ones that give good quality heavy support paper with logos on. I store each project (there are Many) with all the appropriate patterns threads etc in one bag so when I want to continue its all there. For travelling I use the smallest size zip lock bag with fabric thread scissors etc., I just travelled from Australia to U.K. and had no problems with the stitching. And I did pick up some lovely bags in England!!!
