My mother-in-law works at a working historical farm. She works in authentic historical garb, and cooks, spins, and cleans in an authentic historical manner, giving tours to visitors and explaining her processes.
She mentioned to me last year that at the later-season (fall and winter) gigs, her co-worker had a bosom-buddy, or sontag - a historical woolen shawl that wrapped around to allow a woman to work while she wore it. She mentioned that she would like that for Christmas this year, and then she (hopefully) forgot about it.
So, I made one! It's humungous, and I followed a basic pattern from 1860 that I adapted, due to my gauge. I also created a button using Kate Davies Button Tutorial. The garter edge was knit with the body, and when I broke for the "wings," I cast on the 6 stitches needed for the "inside" garter ridges. Later, I went back and knit from the cast-ons, and applied a garter ridge by picking up a stitch from the neck edge, and knitting two together near that edge to maintain the six stitches.
I sent it off to her for a late birthday/early Christmas gift, so she could use it this fall season, and thankfully, she loves it!
