Knitted flat these mitts use short rows to form a circle around the thumb. When I first knitted the Circle Mitts, I thought that it might be a good idea to knit something similar but at right angles to them – while the Circle Mitts are knitted around the circumference, the mitts described here are knitted along the radius.

A video tutorial in Japanese has been provided by Kabosu (かぼすの手しごと) on YouTube. You can find it here (part 1) and here (part 2).

A crochet version of these mitts is available, too: Sparkler Mitts.
