This is one of the stuff sacks I got at the Army Navy Surplus.
It’s got a drawstring at the top, and a handle on the bottom. It weighs practically nothing, and squashes down to about the mass of a walnut. Plus, it’s rip-stop nylon. Perfect for socks.
Lucky for me, I have a lot of sock yarn. Like this lovely skein, which has elastic. And look at those stripes!
Simple 3×1 ribbing, 68 stitches around. And yes, I’m using dpns – because my sock circulars have a different pair of socks on them, but they are already in a bag.
It’s knitter logic.
