I am trying to figure out how to wire a 3-way switch with 2 light fixtures in the middle of a run. The layout is as follows:

Feed - switch 1 - fixture 1 - fixture 2 - switch 2 - feed continues through the end of the run

How to I wire this 3-way and continue the run beyond the 3-way?

Other colors will work, here is an example:
Have All greens/grounds/bare wires intact from first to last box.
Have a black, white and green go in first switch box, to lite 1, lite 2, 2nd switch and out to continue on.
Connections will be the hot to center(common screw on first three way switch), and to black to carry on, blacks tie together in light boxes, it will not make any more connections until after last switch. Whites are tied together and continue on.
Then you need a pair of wires (2 blues?) will be the travellers and will connect from first 3 way switch to second 3 way switch(the 2 same colored screws/not the common).
The light whites connects to the whites in each box.
Last connection will be a yellow(switched leg) this wire connects to common screw on 2nd 3 way and connects to the blacks on each light.
Summay: travellers from switch to switch, and 1 switch will be the hot end(needs constant hot).
Other switch common is the "switched end", and goes to lights. Good Luck.
