Anyone know where I can get union and confederate flag? 

Wasn't sure where to post this. Let me know if this is the wrong section.

You can take any Poser flag prop and re-texture it.  It's really easy to do with something like a flag. 

There are free flags at RDNA and in free stuff here.  Just replace the texture with an image of the confederate flag or the 1861 U.S. flag. 

It's actually really easy to create your own flag (I'm presently creating a scene with a flag). ..if I can do it, anybody can, within Poser. Basically, take a Poser cylinder primitive, scale to taste, go to the setup room and make it a figure. You can add a simple sphere finial to the end of the flag pole.

Go back to the cloth room, load a hi-res plane primitive, scale to taste and line one edge up to the flag pole. In the vertex editor, create a line of constrained vertices on the edge aligned to the pole. The rest of the vertices add to the dynamic group. You can leave everything default for the dynamic group, except change the fold resistance to 20.

Add a wind force object, adjust to taste, try an amplitude of 15 for a start. Let the dynamics do its thing (60 frames should do)...viola! you have your flag.

I created a texture for the flag in Illustrator and Photoshop, but I'm sure there must be plenty of flag textures on the internet.

Obviously a flag attached to draw rope, connected to a pole, would be more complex, but still possible in Poser, by using different dynamic and constrain groups.
