Is it possible to shorten a completed sweater?

I have completed a pullover sweater from a Mary Maxim kit. The person who is receiving it would like it shorter by about 3". Is this possible?

There is a site with very good directions on how to do this. Unfortunately, I’m at work and it is bookmarked on my computer at home. If no one else answers you this afternoon I’ll find it for you tonight, but I won’t be home until probably 8:00 p.m. EST.

Here it is!

That’s the one I was thinking of.
