Really nice pics, especially the second one.

I went looking for July 4th props yesterday for a Golden Retriever event that I have coming up this weekend.

I decided to stay clear of a physical flag in the photo location since I am going to be outdoors and I'm pretty picky about making sure a flag is displayed and treated properly. (which, you seem to have done just fine, so that's not my point )

I may offer an option to PS one in if folks go for the blue screen option over a regular backdrop.

I found a bunch of props at the local dollar store.
