How do you increase in rib pattern
I am working on a basic pullover sweater that is done entirely in rib pattern. The pattern for the sleeve, for example, calls for an increase at each end of row every six rows, sixteen times. How do I increase and stay in the K2R2 pattern? I am familiar with most increases, I just don't quite understand how to make the increases in pattern. Links to any on-line instructions would also be great.
