Oh, yes, a gentleman's socks need to be just right.
Could you please link to instructions for an afterthought heel as you did yours? I'd be most grateful. I'm working toe up so I'll have to be sure my BO is stretchy but I don't have to Kitchener the toe!
I do German short rows and never noticed bumps in the heels. I'll have to pay attention and see if they're there. I'm trying to decide between the Sweet Tomato Heel or Afterthought.
