To me the fact that they are all by the same artist groups them together to me. I have no idea why, but I really like this artist's work! I did think about putting some kind of kids posters or more causal thing over the kids toys. But they have a play room and this will someday be holding something else. I also already have a wall in their playroom that rotates their artwork... So it is done. I got DH to hang them. He says it is very annoying using the clips and you have to really futz with them (and they are still not perfectly straight and he used a level!) . I think I would like to paint the clips. It will be on the someday list :) I can't believe I got them Thursday and they are hung already. Might be a record for us. :)

Your line about "who makes the cut" has really struck a nerve with me. Let me explain. I have the strong opinion that you can do whatever you want with the photos (ie. "who makes the cut"). What you see and how you feel from the displays is all you. A display with a topic theme, color theme, or whatever theme is going to be fabulous as long as you go with your heart and your gut. I had a terrible MIL (EX now!) who actually took the time to inventory WHO was displayed in photos, HOW they were displayed, and concocted her own storylines on why I elected to leave out certain people, include others, and have some more prominent than others. She had the gall to have "sit-down talks" with me several times about my choices in displayed photos. She started sending photos with little post-it notes on where they would "look nice" & which one's I should change out. It gnawed at her to no end that I changed nothing despite her passive-aggressive instructions. I hope your family and/or friends are not the likes of the old hag I used to deal with. You should never, EVER have to explain the reasonings (themes, etc) of photos and why you display what you do. Don't want to bring a downer to this & hope I'm not making you think harder into it. This just brought back some bad memories and it's really too bad it had to go that way. End of therapeutic vent. Gayle

One way to make a particular piece of art stand out is size. In the mockup below, the painting is the largest of the group. Another way is frames. All have black frames except for the painting. Another is color. the painting is multicolored. All the other items in the grouping all have muted colors. So they essentially look like framed black or white piece of paper. I don't think any of the pieces that you have posted would work because the only possibility is the black and white flower but the black is so bold against the white paper, it stands out too much. Also, I see no problem mixing different media in a gallery wall including poster, prints, photos, original art, etc. Here is an example of three black and white photos along with an original painting.

Thanks! I feel better now. I just didn't want to have overkill on the ferris wheels :) I might sit on it a bit before moving them all closer though because what a pain that is to get them up and straight the first time lol. Anyway, thanks for the feedback and making me feel better about it. By the way...that stand is just an old dresser from the 70s that my parents had ditched to the basement at their house. I rummaged it out and redid it. It has been one of my favorite pieces I have. I love that when that happens :)
