This is a machine-knitting pattern which is given as a video in two segments. Diana shows this on the Ultimate Sweater Machine (Bond), a single-bed machine with 8mm spacing between the needles, and it is a beginner project, but intended to be done in a series after the matching scarf and hat. Nevertheless, the videos are clear and one could do the mitten without having done the hat and scarf. The blog entry also contains the following information:

“This is a match-up for the scarf and hat made on the Ultimate Sweater Machine. As you do this mitten, you will practice:

The double e-wrap cast-on
Latching up ribbing
Decreases
Increases
Gathered cast-on for thumb
Mattress stitch steams
Latched trim“

The mitten pattern is available in more sizes with Diana’s book that she sells online.
