from the line of your pattern that can not be told. It says there to knit 17 stitches, then do the double decrease.
what does your pattern continue like? I would not think that it keeps doing more of these decreases in a row.
The decrease lets you get rid of 2 stitches in the same spot, so the shaping would be very drastic if you kept going with it.
How many stitches do you have to beginn with? Knit 17, slip one, k2tog (psso) to me sounds like: 17 + 1 slipped, plus 2 that get knit together.... that was 20 stitches before.
