This is one of the things i really like to do. I like to take a whole bunch of random things and little knicknacks in co-ordinating colors, and then put one piece that's a random color. (notice the one blue button)
YAY glimmer mist...LOVE IT!!!
Liquid glass is also another fav of mine, i used it on the frame in this layout. I also like to use paint on my pages, i added the green paint, it's kind of a nice switch from inking, which i do ALOT of!
I also really like cork accents...you can cut them with your cricut or you can buy them pre-cut, but either way they match any layout and sometimes they just give that little something extra!!!
Another thing i like to do is re-create the background and bring it to the fore-ground, like i did with the cherry blossoms, that way your ideas don't get lost on a too busy page!
