Pretty pattern. Using google translate, but I’ve made mittens in this style before which helps. Two things for English speakers

1. Their are two decreases in the last round of the cuff, marked as black dots in the chart.
2. Designer wants you to knit the pattern from left to right for one mitten, and then from right to left for the second mitten. This is to center the cuff chart.

I’m having difficulty wrapping my head around this second instruction, but I may give it a try when I get to it.

I also reversed the colors. I’m not sure I made an improvement.
