I did a lot of travel when I worked. I would take a few pieces in my purse tote bag will I waited for my flight I would hand piece blocks. I would carry the pieces in several plastic bags, smaller ones for each piece and a larger one for the needle and tread, dental floss (thread cutter) and pins. I then had a larger bag to put the finished blocks into my suitcase when I got to the travel site. Usually when I got home all the pieces I took with me were done. Now that I am retired, I take pieces with me in pencil cases boxes. It also contains my needle and thread etc. I then have a larger plastic tote that I put the finished pieces in till I get home. Works great. Good luck.
