What is a "3 needle BO"?

I’m just finishing up this vest and have gotten stuck…can anyone please help me?

Here’s the pattern: http://knitty.com/ISSUEspring04/PATTboogie.html

Under the part, “Join Shoulders,” it says: …work a 3 needle BO to join these sts…

How exactly do I do this?

Thanks for your help! :smiley:

Okay, I’m a dork. I can’t believe I didn’t look there before posting my question! :oops:


Can I just say I love 3 needle bindoff. I wish I could do all my seams that way.
