Pattern help!

I am making the Jacobus monkey from Ravelry and i’m having trouble with one of the directions in the pattern and i’m hoping someone can help me with them. Here is what is says:

[B]* Increase one sts by reversed knitting of the thread between the 2 underlying sts[/B]

I know how to increase in various ways, but for some reason I just can’t seem to figure out what kind of increase she is talking about here. If anyone can help i’d would be very grateful. Thank you very much!

Such a cute monkey!

Does the pattern give instructions? Sometimes they do. The designer is Dutch and sometimes other cultures use different terms for the same thing.

I bet a “pick up the thread between stitches and knit into the back loop”. Here’s a video

Yeah, I think it’s a regular m1 - lift the yarn between sts and knit it through the back.
