In early 2022, my sister moved halfway across the continental US. As a result, I spent quite a bit of time at airports and on airplanes that year. More so as a direct flight is not an option.

These socks came out of those trips and the lessons I learned. No picking up of stitches, no special stitches, and if you can read your knitting, no markers necessary. A tapestry needle will be needed at some point for weaving in of ends but is not needed to finish off the live stitches (dental threaders will work in a pinch).

Caveat -
At the time of publication, knitting needles are specifically listed as allowable on domestic flights within the US. Please check and follow the applicable guidelines for the country(ies) and/or airlines involved with your travel.
