OK, not that plain:
One aspect of my self-care plan for the year is to indulge in more plain stockinette socks. For ME. As a dyer of fine sock yarns and a reasonably accomplished knitter, the fact that I own almost no socks (let alone handknit ones) seems.... dumb. And stockinette socks in warm and lavishly varied hues are such a delightful indulgence, not to mention being virtually foolproof knitting for the bouts of headache and brain fog. I didn't think I'd be so entertained by a colourway I dyed myself, but I'm finding a great deal of joy in the little surprises of hue and shading, bursts of juicy colour and subtle blending around every bend.
I'll knit some for the rest of the family too, but Rob only wants sombre semi-solids, which are no fun, and the kids grow out of their socks so fast (well, to clarify, I wish my daughter would grow out of hers - she likes to floor-skate when they're wet and wear savage holes in the soles in no time.) For now though, I'm knitting for me.
