Here are socks knit since the original posting: the linen socks that got very worn got mended and worn again. But in July I bought some more linen and started another pair – on the green needles. I will be able to wear them over knee socks in the cool months. The bulky pair of amber are pure wool; the lightweight pair of amber are from a cone of rayon, a fibre archeology find at a church sale, likely from someone's stash in the Seventies. The steel oatmeal socks are acrylic – pilling a bit, as acrylic can do, but nicely serviceable.
