Hi,
My pattern states for 74 stiches P1, *K12, [yf, K2tog] 6 times, rep twice more P1.

Then the next row states K1*P12,to twice more, K1.

Once I K2tog I don’t have enought stiches left for the 2nd row because I have decreased them all off.

The pattern should be a ripple pattern or simlar to a wavey line but I can’f figure it out.

It is a NORO pattern from the World of Nature.

Can anyone give me any help with this?
Thanks,
Ruth

The ‘yf’ is yarn forward which is the same as a YO and adds the st the k2tog takes off. A YO is done by wrapping the st around the needle as for a knit st, then do the k2tog.
