another pattern question
I'm a relatively new knitter and I'm trying to figure out a pattern from the 365 Knitting Stitches a Year calendar. For the March 22 butterfly lace pattern, I start out with 31 stitches cast on (multiple of 8 +7). After following the instructions for row 1 I come out with 27 stitches. I have no clue where I'm going wrong. I knit 2 stitches together when it says to. My problem may be in the yarnover, which I'm still very new at. The pattern saysfor row 1 to K1, *K2tog, YO, K1, YO, sl 1, K1, psso, K3 rep from * to last 6 stitches, K2tog, YO, K1 YO, sl 1, K1, psso, K1. When it says to yarnover, do I knit 1 with the yarnover and then knit another one for the K1 or not? I'm not sure if I'm explaining this well enough. Any help would be REALLY appreciated!
