The roving is from a grab bag I bought from Left Hand Pinkie on an impulse. It decided to be sock yarn. It was spun very fine and Navajo plied it to maintain the color stripes. I call them Free Socks because the yarn got named "I Spin Freely" yarn. I did pay for the grab bag of roving, so they aren't free in that sense.
The ideas behind the design of the socks (but not an actual pattern) can be found in this post. Info on how the yarn was made can be found here.
