How to Wire Three Way Switches and 3-Way Dimmer Switches

3 Way Dimmer Switch Wiring Variations
Electrical Question: I am wiring a circuit using 3 way dimmer switches.
The power goes to the first switch, then to a number of cans in the ceiling, then to the second switch.
I pulled 12/3 as I would with a single fixture, but am confused as to how I wire the multiple fixtures, since there is not a solid traveler from the powered switch to the remote switch.
Help!

Additional Comments: Thanks!

Thanks for your electrical question Mark.

How to Wire Three Way Switches and Dimmer Switches

Mark, you just explained the problem – the way that you have wired does not provide the necessary travelers between the 3 way switches.
Sure, you can run the travelers through the light fixtures, but this is not the ideal way.
