People have asked me the meaning of DH: it stands for "Dear Husband." As in, love of my life, my dearest heart, my completion, my everything: The Man in the Houndstooth.
It's a blog convention, and kind of a silly one I guess. I thought it was started by knitters somehow (multitudes of knitters have blogs). Elizabeth Zimmerman called her husband "the Old Man" in her iconic book Knitters Almanac and that is maybe where I got that notion (pun- "notion" -for you crafters).
Since I am trying to remain basically anonymous on this blog, it seemed like a good idea- but maybe I should find a different name for him. Besides his own, I mean, or "Brain" (which he has earned, BTW), which often garners me the well-meaning comment, "You spelled your husband's name wrong." Not wrong, exactly, just skewed, and true.
