I am knitting a hat and the pattern calls for
K9, k2tog, repeat
K8 k2tog, repeat
I missed a knit even row : (
K7 2 tog
K6 2 tog
I am I new knitter and don't want to rip out the two rows because I know I will mess it up. so is it better to
knit 2 even rows and continue
or just continue with
K 5 2tog
It is up to you. Me, I would unpick the rows and redo them but I don't like seeing my mistakes every time I look at the finished item.
If you really don't want to unpick, either of the solutions you have proposed will work. If you want the crown to be the same length it would have been if you had not made the mistake, start with two knit rows.
If the length of the crown is not an issue, then just start with the decrease row.
