Thanks so much for your speedy response.
The patten says K5, k2tog, K1, yfwd, sl 1, K1, psso
It's a baby cardigan and it does have a decorative pattern. It's like a cluster of three little holes throughout the cardigan.
But it does not use the expression yo.
So, am i to understand, that if there isn't a decorative pattern, then you put the yarn forward as if doing purl stitches and only put it over the needle when there is a pattern?
By doing the yfwd you will be making the stitch without making a hole. it will wrap itself over the needle when you next do a Knit stitch. Any clearer?
