Baby hoodie-HELP!!!

THis is the link to the pattern I'm doing-


http://cache.lionbrand.com/patterns/...html?noImages=

I'm at the end of doing the back, and it says:

K8 (10, 11, 14), attach second ball of yarn, bind off 22 (22, 24, 24), k8 (10, 11, 14).
Working both sides at the same time, work 2 rows even. Bind off.

How do I work both sides at the same time when there are 22 bound-off stitches in between them?? I tried just knitting regular, but there was a big long strand in between the two sides and I'm not sure that's right.

Thanks!
Nicole
