Week #3 is "Necktie for Gentleman" From Weldon’s Practical Knitter, Thirty-Fourth Series (c. 1900). “The most suitable colors are olive green, grayish blue, dark red, dark blue, and black. One ball of knitting silk, if it contains an ounce, will be sufficient for one necktie, so the cost will not be excessive. A pair of steel knitting needles, No. 14, will also be required.”
Scarf is knit in k2, p2 ribbing, or in moss stitch (as illustrated) “These neckties stretch considerably in wear, so it is well not to make them too long at first”
I am going to use a fingering weight yarn, will see if I have a silk blend I can use, and US size 2.5 (3 mm) needles. I'm going to knit in the Moss Stitch rather than ribbing.
I didn't have any silk or silk blend yarns in the stash, but I found two skeins of Koigu Painter's Palette Premium Merino, a hand-painted fingering weight merino wool yarn. The blue colors are very gentlemanly.
