As a fanatic sewer and quilter, I hate being without a sewing machine when I travel. My hands get antsy and withdrawal symptoms set in like a smartphone addict without their cell phone. Ever since my first laptop, I've wondered why there are no laptop style sewing machines.
Quilters travel for classes, quilt group get-togethers and retreats, not just for vacations. Serious sewers don't like lugging their heavy machines around or risking the delicate electronics. There is a large fan base of Singer Featherweight sewing machine aficionados.These are lightweight (if you consider 11 pounds lightweight) machines made up to 1964 and have a retro charm.
Others buy modern brands of lightweight machines, but these are in the same weight range which rules out taking them on international flights where they strictly monitor baggage weight. On my recent flights, they weighed all carry-on luggage, including purses, and totaled the combined weight.
But there is hope for the future! Have you seen the Flat Mode sewing machine which won a design competition?
It uses a bluetooth foot pedal, folds flat and can be carried in one hand. It won first prize from the Manufacturers Association of Israel in 2004. The Flat Mode machine was designed by Itay Potash, but I can't find any sign that it is yet being manufactured en masse.
