Some of our pictures

Here are some of the pictures we had taken a couple weeks ago by Kylie and Trent's friend. The boys loved the train yard and climbing on the trains.

Help with Pictures

I think I am going to use a layout similar to the second one down for our family pictures going up the stairs. But I am wondering if I can mix black and white pictures with color pictures?? Some of our pictures I like better in black and white - but I don't want the whole wall grouping to be black and white pictures. The B&W would probably be mixed through out. Hard to explain which ones are which but B&W would be the horizontal rectangle beneath the biggest square on top, then I am doing another horizontal rectangle above the two tall vertical one where there is now just a little square, that would be B&W and then the bottom biggest square would be B&W. Tell me what you think about mixing B&W with colored pictures.
