thumb translation

I just read the last entry, and felt that I of course have to share the translation I have of the thumb part. Now, my pattern was in dutch, so it is translated from dutch. (Thank you, knitting nederlass!) I hope it's helpful!
Here it is:

Continue to knit all stitches in fantasy rib, except for the 13 thumb sts
that you knit in stockinette.
Decrease on both ends of the marked stitches every second row: 6 times a
simple decrease (slip 1, knit 1, psso on the two stitches before marked
stitch and knit together the 2 stitches that follow the marked stitch.) Then 2 rows up, knittog the purl stitch and the marked stitch.

At 9 cm total length, the edge stitch. Place stitch marker and increase on
both sides. (at the same time steadily forming a rib stitch on the increased
stitches.)
