This was a great solution for displaying the mish-mosh of artwork I had stored in my basement. I chose black & white and color photographs, original artwork by yours truly, and added a painted letter "P" for dimension. The frames are a mixture of black, silver and dark wood tones.

Tip: Don't be shy about putting it all out there! Eclectic is in, and a good layout will make mismatched pieces work in harmony. Trace each piece onto some posterboard and move your "templates" around on the wall until you find a layout that's appealing to you.
And ignore your husband's cries about putting a million holes in the wall; when your friends start gushing about your gutsy decor, he'll forget all about the holes!
