Started 40stitches, knit 10cm 1st, 1pst, continue knit wise stitches til you reach your thumb starting point. I used markers for 10cm point and thumb hole, so it would be easier to knit other mitten too :)

Thumb hole:
at thumb hole, knit 10 stitches, then take 6 stitches off to another yarn or use safety pin like i did.

Stitch 2 rounds in st, next 2 rounds knit together 2 stitches @ the end/start point.

Knit til you have reached your tiny fingers tip, start stitching together every row start and end til you have knitted to your pointing fingers tip. Finish the mitten by stitching together on both side ends :)

Start thumb with 16 stitches :)
Finish thumb :3
