Pattern question

This is the 4th row of a baby skirt from Leisure Arts. It reads in part “…YO, k1, work knit increase, k1, YO…”

Is the increase worked on the k1 stitch or is it worked on the next stitch? In other words does the sequence above worked over 4 stitches or 5?

Welcome to KH. Your pattern should specify how you’re to make increases. If you can compare stitch counts at the end of the row you’ve just finished and the one you quoted that could help figure out how it’s to be done.

Also remember that a yarn over does not use a knit stitch. It is simply wrapping the yarn over the needle and brought to the back again.

Thank y’all so much! Thanks to y’all’s advice, I was able to figure it out!
