I did solve the mystery of why they are known as Bavarian socks - apparently this kind of traveling stitch is referred to as Bavarian knitting. I must admit I never noticed any socks like this while I lived in Bavaria, but then, I was raising small children and I don't remember noticing socks at all, unless the baby was kicking one off.
Because all this twisting eats up yardage, I don't expect them to be the usual mid-calf length I prefer. And since they are cuff-down, I'm having to guess how long I can make them. But I've turned the heel on this first one since I took the picture (they live at my desk, so photo opportunities are slim).
I really like the way the designer arranged the heel flap stitches to grow out of the established pattern. They're going to be very nice. Eventually.
I've also taking this yarn and roving, and begun thrummed mittens (from a kit bought at the Adirondack Museum). Sharp-eyed readers will note that Stewart-Pasha is assisting with the photo shoot. During my first attempt at the pattern, I made the thrums way too thick. Also, the short rolled cuff seemed like a terrible idea for cold winter days. But I had just enough yarn left from the recent hat to make ribbed cuffs to attach. And I figured they'd given me just enough roving for the thrums and divided it up accordingly, and now things are going better.
Both projects have been ignored lately in favor of a baby gift, because babies don't wait. Fortunately, they also don't take much time.
