No one has mentioned something travelers would find useful-a roll up carrier for electronic cords. I made one for both of my daughters a few years ago. I don’t recall where I found the pattern, but it consists of elastic pieces sewn in rows to hold cords for phones, Kindle or other pads, etc. I quilted the outer layer of these & they turned out cute.
I bought a heavier-duty one of nylon to carry in my motorcycle saddlebag for my long trips. It’s always full when I travel. I used to put all cords in a plastic ziplock, which usually got holes from the plug ends. This type of roll up prevents that issue.
